Hello everyone, I want to split the matrix in such a way that when elements of 1st column are equal, the correspnding elements can be splitted into another matrix. For example, i have the following matrix.
A = [ 1 2; 1 3; 1 4; 2 1; 2 4].
i want to get the following 2 matrices as the resulting matrices.
a1 = [2;3;4] and a2= [1;4]
i have just started learning the looping in MATLAB, your coperation will be highly appreciated.

A = [ 1 2; 1 3; 1 4; 2 1; 2 4]
[ii,jj,kk]=unique(A(:,1),'stable')
out=accumarray(kk,A(:,2),[],@(x){x})
celldisp(out)

I mean your question is not clear, why do you need a for loop, when accumarray can do the job?
