MATLAB: How to write linear equalities in GA ? – please answer please

Question

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

so what should I write in nvars section? actually,how can I show 6*6 matrix in nvars section ? or should I write just 1 ?

then, I have a const like

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

x(1,1)+x(1,2)+x(1,3)….+x(1,6)=1

x(2,1)+x(2,2)+x(2,3)….+x(2,6)=1

.

.

x(6,1)+x(6,2)+x(6,3)….+x(6,6)=1

how can I write this in ga ?

Answer 1

nvars should be the total number of unknowns, so 6*6 = 36 in your case.

Linear equalities are expressed through the Aeq beq argument pair.

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