Add colorbar next to image
from mpl_toolkits.axes_grid1 import make_axes_locatable
def colorbar(mappable):
"mappable is img = plt.imshow()"
ax = mappable.axes
fig = ax.figure
divider = make_axes_locatable(ax)
cax = divider.append_axes("right", size="5%", pad=0.05)
cax.aname = 'colorbar'
return fig.colorbar(mappable, cax=cax)

Remote Jupyter Notebook through ssh tunnel

Using Jupyter notebook remotely via a ssh tunnel.

Especially good for running on headless devices, such as supercomputers or clusters.


# remote_port should be value between 8888 and 9000
jupyter notebook --no-browser --port=remote_port

Locally, new terminal window

bencholmes / forceFFTSymmetry.m
Created Aug 30, 2018
A MATLAB function to force symmetry on an FFT, thus producing a real signal after an IFFT.
View forceFFTSymmetry.m
function X = forceFFTSymmetry(X)
% forceFFTSymmetry A function to force conjugate symmetry on an FFT such that when an
% IFFT is performed the result is a real signal.
% The function has been written to replace MATLAB's ifft(X,'symmetric'), as this function

Checkout github pull requests locally

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url =

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

You can’t perform that action at this time.
