Importing colormaps from python (matplotlib) into Matlab on Macbook

2022-09-06T23:50:35-04:00

This post shows step-by-step instructions on importing different classes of colormaps from python (Matplotlib) into Matlab using PyColormap4Matlab.

Download the PyColormap4Matlab library from the following link: https://www.mathworks.com/matlabcentral/fileexchange/68239-pycolormap4matlab
Rename the package to PyColormap4Matlab,
Copy & paste the new folder in your Documents as /Documents/MATLAB/PyColormap4Matlab,
Open the MATLAB application and link the new folder PyColormap4Matlab to it using the "Home > Set Path" tab in the top menu. Next, click "Add Folder" and select /Documents/MATLAB/PyColormap4Matlab, then click on Open, Save, and Close.
Install the “Matplotlib" library. To do so, enter the command "pip3 install matplotlib" in the terminal. For other options, check https://www.geeksforgeeks.org/how-to-install-matplotlib-on-macos/
Now, you can import the colormaps from Matplotlib to MATLAB. The following MATLAB script imports the colormap Greys from Matplotlib to MATLAB. The name of the new colormap in MATLAB is cl_Greys:

# set the Python path
path_python = '/usr/bin/python3';
# importing Greys colormap from Matplotlib
cl_Greys = getPyPlot_cMap('Greys', [], [], path_python);

Hint: to find the Python path (for variable "path_python") enter the "which python3" command in the terminal.

For a list of Matplotlib colormaps, check the following link: https://matplotlib.org/stable/tutorials/colors/colormaps.html
In the following pictures, prepared by Kamyar Mohseni, different classes of Matplotlib colormaps are compared together and also with MATLAB colormaps.

How to run multiple programs in a sequence using a bash script?

2018-06-27T02:11:40-04:00

How to write a bash script that goes through each subdirectory inside a parent_directory and executes a command in each subdirectory?

Suppose there are 10 subdirectories inside a parent_directory with the following structure:

***parent_directory (name could be anything - doesn't follow a pattern)

— subdir1 (subdirectory names follow a specific pattern, e.g. fixed characters + number)
input.data (input of the code)
code.f (main code, here is a Fortran code)
Makefile (makefile to execute and run the code)
— subdir2
input files + codes + Makefile
— subdir3
input files + codes + Makefile
.
.
.
— subdir10

Suppose we want to run the codes in the first five subdirectories, i.e. subdir1-subdir5, wait for the processes to finish and then continue running the codes in the next five subdirectories, i.e. subdir6-subdir10.

The example of the bash script is as (download the bash script file ):

#!/bin/bash
## exit on the first error.
set -e

# Add the full path of parent_directory to run the codes in the subdirectories
path=$(pwd)
## just for checking the path of the parent_directory
echo path= $path

## the min and the max values of the int variable i, changing from 1 to 5
i=1
imax=5

## do loop from i to imax
while [ $i -le $imax ]; do
## path of each subdirectory defined as "subdir" + integer i
pathi=$path/subdir$i
## just for checking the path of each subdirectory
echo pathi= $pathi
## cd to each subdirectory of the loop
cd $pathi
## compile and run the code in each subdirectory using Makefile ("Main" is the executable file)
make -f Makefile
nohup ./Main &
## adding the counter
let i=i+1
done

## Wait for the processes to finish
wait

i=6
imax=10

## do loop from i to imax
while [ $i -le $imax ]; do
## path of each subdirectory defined as "subdir" + integer i
pathi=$path/subdir$i
## just for checking the path of each subdirectory using Makefile ("Main" is the executable file)
echo pathi= $pathi
## cd to each subdirectory of the loop
cd $pathi
## compile and run the code in each subdirectory
make -f Makefile
nohup ./Main &
## adding the counter
let i=i+1
done

You can run the bash script (called "run.sh") by:
$ bash run.sh

How to copy a file to all subdirectories in a directory using a command-line?

2018-06-26T13:32:06-04:00

This will put the file "code.f" (in the current working directory) in all of the subfolders, but not their subfolders:
for d in */; do cp code.f "$d"; done

But this will put the file "code.f" in all of the subfolders and their subfolders:
find . -type d -exec cp code.f {} \;

How to delete all files of a specific extension in a directory and all subfolders using a command-line?

2018-06-26T12:54:28-04:00

To remove all files with a specific extension (e.g. .data) in the current directory and all subfolders run
find . -name "*.data" -type f -delete
But first use "find" to see exactly which files you will remove:
find . -name "*.data" -type f

Run gedit on Mac OS X Mavericks

2014-03-24T22:00:09-04:00

1) Download the last version of gedit (gedit-3.2.6-3) from gnome.org for Mac OS X (Click here for direct download link).
2) Install gedit application.

To solve the problem of running gedit on Mac OS X Mavericks, we need to update the version of libxml2 packaged with gedit as follow:
3) use the command
$ brew install libxml2
4) and then
$ cp /usr/local/Cellar/libxml2/2.9.0/lib/libxml2.2.dylib /Applications/gedit.app/Contents/Resources/lib/
point: If in the last step, you get the error message
“cp: /usr/local/Cellar/libxml2/2.9.0/lib/libxml2.2.dylib: No such file or directory”
you need to check the version of installed libxml2 on your system (here it is supposed to be 2.9.0) and change the version in cp command.

Search not working properly in mail (Mac OS X)

2013-10-28T21:57:01-04:00

If there are problems with information in your mailboxes, you might see an alert message saying that Mail needs to repair your mailboxes by reindexing your messages for you.
At other times, you may want to reindex messages yourself—for example, when searching mailboxes using Subject, To, or From doesn’t return the correct results.

1) Quit Mail if it is open.
2) In ~/Library/Mail/V2/MailData, delete any file that begins with “Envelope Index,” such as Envelope Index, Envelope Index-shm or Envelope Index-wal.
3) Your home Library folder is hidden by default. To display it, choose Finder > “Go to Folder” and then enter “~/Library”.
4) Then open Mail. Mail creates new Envelope Index files. This process may take a few minutes, depending on how many messages Mail is reindexing.

Install Dropbox via command line on Linux

2013-09-24T21:49:46-04:00

The Dropbox daemon works fine on all 32-bit and 64-bit Linux servers. To install, run the following command in your Linux terminal.
32-bit:
$ cd ~ && wget -O - "https://www.dropbox.com/download?plat=lnx.x86" | tar xzf -
64-bit:
$ cd ~ && wget -O - "https://www.dropbox.com/download?plat=lnx.x86_64" | tar xzf -
Next, run the Dropbox daemon from the newly created .dropbox-dist folder.
$ ~/.dropbox-dist/dropboxd
Tip:
If you're running Dropbox on your server for the first time, you'll be asked to copy and paste a link in a working browser to create a new account or add your server to an existing account. Once you do, your Dropbox folder will be created in your home directory. Download this CLI script to control Dropbox from the command line. For easy access, put a symlink to the script anywhere in your PATH.

Matlab loads, but "freezes" after taking Java update in Mac OS X

2013-09-17T21:48:00-04:00

After taking the Java update via the App store, Matlab will launch and open the last file, however, it will freeze and don't open any file. This is a Java issue and reinstalling Matlab or a new user profile will not resolve.
Context - Affects MATLAB 2012b and earlier, with the Java for OS X 2013-004 update - The original update gives build 1.6.0_51-b11-456-10M4508 - This can be verified by running the command below in terminal and comparing the build
$ java -version
Good:
Java(TM) SE Runtime Environment (build 1.6.0_45-b06-451-11M4406)
Java(TM) SE Runtime Environment (build 1.6.0_51-b11-457-11M4509)
Bad:
Java(TM) SE Runtime Environment (build 1.6.0_51-b11-456-10M4508)

SOLUTION - Apple's update has been fixed, however, it is not being pushed via updates to clients already affected. It is now safe to update via the Appstore, Java for OS X 2013-004 is the package. - If you are stuck on version 10M4508, you can manually update:
* for 10.7/10.8: http://support.apple.com/kb/DL1572
* for 10.6: http://support.apple.com/kb/DL1573
