Hi!i have a matrix 136*136 that for each cell contains a value. This value is the index of a column of another matrix(24*391) that is associated. Now i want associate for each cell(136*136) the column vector and obtain a multidimensional array.. Any ideas?

Hi!i have a matrix 136*136.

Call this A.

This value is the index of a column of another matrix(24*391)

Call this B. Then,

result=reshape( B(:,A).',  136,136,[]) ;
