eval3d

values of a function on a grid

Calling Sequence

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);
