I would like to know how to integrate a 2D griddedInterpolant with respect to one variable.
I include an example:
[x,y] = ndgrid(-5:0.8:5);
z = x.^2 + y.^2;
F = griddedInterpolant(x,y,z);
The actual interpolant is from data and not availbe in a closed analytical form.
This produces an error. Is there a simple alternative?
