Hello
https://www.mathworks.com/help/optim/ug/two-dimensional-semi-infinite-constraint.html
what if w2 is between 1 and 199 instead of 1-100? In that case wx and wy would have different sizes and it would throw an error at K1.

you could modify s(1,1) to 1 so wx and wy will have a size of 100 at start, but as we know s is changing between calls, so they can have different sizes during the execution

w1x and w1y would have different sizes, but not wx and wy.

So the key is that wx and wy is created with meshgrid from w1x and w1y

Can you create n dimensional semi infinite constraints too instead of two dimensional constraints by using ndgrid instead of meshgrid?

yes. The number of elements created by meshgrid (or ndgrid) in the arrays wx and wy equals the number of grid points in two (or n) dimensions - and that's where the constraint is evaluated.
