I'm trying to solve a double integral using the trapezoidal rule. I was told to use this file exchange 2D trapezoidal rule to help solve it and the code
x = 0:0.1:1;
y = 0:0.1:1;
[X,Y] = meshgrid(x,y);
F = @(x,y) 1;
Z = F(X,Y);
Z(Y > sqrt(1-X.^2)) = 0;
Either the code is not working or I'm just not sure how to get it to work with the function in the file exchange link.
The integral I'm trying to solve is this.
Any help would be appreciated.
