Linux – How to pass variables between bash scripts and Matlab

For example, in Matlab, I have a string x = 'foo' so I want to use it in a bash script. Or I have x =$'foo' in the bash script so I want to use x in Matlab. Is there a way to do this?

I can’t tell you about matlab, but in Octave everything is simple.

For example, to pass a bash variable to octave, all you need to do is this:

Xmax=10; echo "x=[1:$Xmax]; sin(x)" | octave -q
ans =

Columns 1 through 8:

0.84147   0.90930   0.14112  -0.75680  -0.95892  -0.27942   0.65699   0.98936

Columns 9 and 10:

0.41212  -0.54402

And vice versa:

Xmax=$(echo "fprintf(1, '%g', max(sin([1:5])))" | octave -q); echo $Xmax
0.909297
