I have the following cell array as matrices for its content. Matrices are of variable dimension.

c{1} = [1,2,3];
c{2} = [2,3,5,6];
c{3} = [1,2];

What is requires is to sort the given cell array 'c' according to a index vector.

if index vector is idx,

idx = [2;3;1];

I want the cell array 'c' to look like

c{1} = [2,3,5,6];
c{2} = [1,2];
c{3} = [1,2,3];

I tried using the command

c = c(idx);

which should work if c were a numerical array, but the command returns in an error. How do I get about this?

Thank you.

What was the error message? It works without any problem.

change semicolon to comma to seperate 2 & 3 from id:

idx = [2,3,1];

Semi colon or comma both works.
