definition of nonlincon in the fmincon function
显示 更早的评论
Hi guys, I'm having trouble in defining the nonlincon when one of my nonlinear constraints is not the same size as the others. When I run the code it says error CAT argument. please how should I consider that? Thanks.
function [c ceq]=nonlincon(x)
c(1) = with m variabels x(1),..,x(m) : size[1,m]
c(2) = with n variables x(1),...,x(n) : size [1,n]
ceq=[]

Hi Mohammad,
The c output in your nonlincon function should be a vector or matrix, where each element of c is less than zero.
In your case, you should just be able to change your current function (note that I've changed the notation in your second vector) from:
function [c ceq]=nonlincon(x)
c(1) = with m variabels x(1),..,x(m) : size[1,m]
c(2) = with n variables y(1),...,y(n) : size [1,n]
ceq=[]
to:
function [c ceq]=nonlincon(x)
% Return a 1-by-m+n vector containing the constraints in your
% original "c(1)" and "c(2)"
c = [x, y];
ceq=[]
Hope this helps.
Best regards,
Paul
