Question

I’d like to create new vectors from columns of an existing matrix. My code looks like:

Matrix=[1 2 3;4 5 6;7 8 9];
A=Matrix(:,1);
B=Matrix(:,2);
C=Matrix(:,3);

I see that this code is not really elegant especially if I have a big number of columns, that’s why I’m looking for something like:

[A B C]=Matrix;

But Matlab said the matrix can’t be assigned to multiple values. Is there another way?

Answer 1

use mat2cell to split your original matrix up and deal to assign the splitted data to the result variables A,B and C:

m = mat2cell(Matrix,size(Matrix,1),ones(1,size(Matrix,2)))
[A,B,C] = deal(m{:})

Unfortunately the intermediary variable is needed (however there is the FEX function dealcell that solves this if you like one-liners)
