finding text in files using find in linux
By thomas in linux, ubuntuBased on this stack-overflow response: http://stackoverflow.com/questions/16956810/finding-all-files-containing-a-text-string-in-linux
one way of searching for files containing a certain text patterns is:
grep -rnw ‘directory’ -e “pattern”
if you want to search relative to your current position replace “directory” with a . so:
grep -rnw . -e “pattern”

Matlab: calling a function handle with parameters from a cell array
By thomas in matlabHaving a function handle sometimes means that you want to be flexible regarding the number of input arguments.
having a function handle fhandle=@plot
means that you can call fhandle() but is you want to pass a variable number of arguments to fhandle that resides in a cell array, cparameters, containing e.g.: cparameters={[1:10],’resize’,’no’} you can do:
fhandle(cparameters{:}) which will result in e.g. plot([1:10],’resize’,’no’)
In the case where you want additional stuff to happen – e.g. add title to the plot you can do:
fhandle=@(data,titlestr,varargin) plot(data,varargin{:}) && title(titlestr)
cparameters={1:10,'test title','LineWidth',5}
fhandle(cparameters{:})
Will produce
plot(1:10,’LineWidth’,5) && title(titlestr)

plot functions in mathematica
By thomas in Mathematica, Uncategorizedcontour plots can be used in mathematica to plot equations such as ellipsoids like:
1/10^2*x^2 + 1/6^2*y^2 + 1/15^2*z^2 == 1
a command like:
ContourPlot3D[
1/10^2*x^2 + 1/6^2*y^2 + 1/15^2*z^2 == 1, {x, -11, 11}, {y, -7,
7}, {z, -16, 16}]
creates the ellipsoid

By thomas in GITIf you have a git repository that consist of several submodules you can push all submodules by doing the following:
place yourself in the main git repo.
write:
git submodule foreach git push
To make sure that you get through all the submodules even if errors occurs do:
