I want to plot a 3D surface , but I cannot apply the surf() command straightforwardly for some reason.
I have two vectors for x and y coordinates. Let us say
x = linspace(-10, 10, 100);
y = linspace(-0.5, 0.5, 100);
To calzulate I have to call some function which works only for fixed values of x and y. Thys, I calculate it as follows
func(i,j) = @MyFunction(__some_parameters__, x(i), y(j));
As a result I have two vectors for x and y and a matrix of the size length(x)*length(y) for the variable z. Could you tell me please, if there are any convenient methods to rewrite this data to a format that is appropriate for applying the surf() command?
P.S. I used plot3(x(i), y(j), func(i,j), 'b.') with two cycles, but it is a ridiculous "dirty hack" and not a surface.
