How to define function include others functions in matlab

1 view (last 30 days)
Assume I have 2 complicated function X(u) and Y(v). How to define R(X,Y) function, then I can get integral of R(u,v)?
For example
X(u) = 1-u
Y(v) = 1-v
R(u,v) = sqrt(X^2+Y^2)

X = @(u) 1-u;
Y = @(v) 1-v;
R = @(u,v) sqrt(X(u).^2+Y(v).^2);
%Integrate R w.r.t u from 0 to 1
%and w.r.t v from 1 to 2
integral2(R, 0, 1, 1, 2)
ans = 0.7652
