How can I write sum(j,x(i,j))=1 in GA ? - please answer please

In my problem I have x(i,j)-(6*6) matrix and I want to solve the problem with global opt. tool.

then, I have a const like

sum(j,x(i,j)=1 , likely you know,but it's mean;

x(1,1)+x(2,1)+x(3,1)....+x(6,1)=1

x(1,2)+x(2,2)+x(3,2)....+x(6,2)=1

.

.

x(1,6)+x(2,6)+x(3,6)....+x(6,6)=1

how can I write this in ga ?

I can write sum(i,x(i,j)) by;

T = ones(1,6);
Aeq = blkdiag(T,T,T,T,T,T);
beq = ones(6,1);

I am not sure that I understand what you are asking. You seem to know about Aeq and beq and their syntax. Is what you want a way to turn your x variable from a matrix to a vector? Basically, ga insists on each x variable being represented by a row vector. See Matrix Arguments, which discusses how linear constraint matrices view constraints.

In other words, I think that the answer to your question is to properly interpret your matrix of x(i,j) as a vector x(i) for a longer index i. But maybe I misunderstand.
