Can I use two dimensions as upper and lower bound in GA code to solve a minimization optimization poroblem?

I have a finite element mesh of a rectangular plate. The nodes on the plate is the spring locations and they are my constraint. I have upper and lower bounds on the nodes in x and y axes. How can use GA to solve such problem. In case of one dimension, I can straightway use lower and upper bound since I can specify them in the default algorithm of GA. Please help.

The lb and ub input arguments are allowed to be vectors. If you have N unknowns with upper and lower bounds, just make lb and ub vectors of dimension Nx1.

Thanks Matt for ur reply. I have lower and upper bounds in two dimensions viz. x n y. How do I incorporate those as a vector of lb n ub??

[Matt J]

For every unknown u(i), it will be bounded as lb(i)<=u(i)<=ub(i) for all i=1...N where N is the total number of unknowns.
