Hello

What can you do if the constraints have higher dimension than 2?

Here

https://www.mathworks.com/help/optim/ug/two-dimensional-semi-infinite-constraint.html

is the 2D example, but in my problem I have products like

... . Not exactly this but the point is that I have n number of

and I have to multiply all of them(not only 2 of them).

Seems like transforming the constraint matrix into a lower dimension form doesn't work, I tried adding this line after K1 is assigned in the two dimensional example

K1=K1(:);

and the solution I get from fseminf is not a valid solution even though the matrix elements are the same.

[c,ceq,K1] = mycon(x,[0.5,0.5]);  % Sampling interval 0.5
max(max(K1))

returns a positive number

Hello,

were you able to solve this problem with 3D constraint matrix?

Thank you in advance.

If you have one inequality (doesn't matter how the lhs is computed, with finite or infinite series or products), then you have ONE constraint.

I have more than 1 inequality, all of them looks similar to the others, like this

phi_phi2,phi3 correspond to
