Question

I ve got a matrix and i want to split is in the columns vectors. I want to have as output the
above vectors [a b c d e f g h k l m n o p q r s t u] and as an input the matrix A. is there any idea?

Answer 1

You can do this by converting your matrix to a cell array as follows:

M = rand(4);            % create a 4x4 random example matrix
C = num2cell(M,1);      % convert every column to a cell
[a,b,c,d] = deal(C{:}); % assign to variables a...d

This results in four column vectors a, b, c, d. Add more letters as needed.

I’m not really sure why you would want to do this though, I think it’s probably more efficient to just index your original matrix with the column number you need.
