eval3d
values of a function on a grid
Calling Sequence
[z]=eval3d(fun,x,[y])
Arguments
- fun
function accepting vectors as arguments.
- x,y
2 vectors of size (1,n1) and (1,n2). (default value for
y:y=x).- z
matrix of size (n1,n2).
Description
This function returns a matrix z(n1,n2). z(i,j)=fun(x(i),y(j)).
If the function fun does not accept arguments of type vector use the
primitive feval.
Examples
x=-5:5;y=x; deff('[z]=f(x,y)',['z= x.*y']); z=eval3d(f,x,y); plot3d(x,y,z); deff('[z]=f(x,y)',['z= x*y']); z=feval(x,y,f); plot3d(x,y,z);
