Hi everyone!
I've written a matlab m-file to draw a double integral as below. Does everybody can show me its equivalent in mathematica???

Collapse | Copy Code

tetha = pi/4;
lamb = -1;
h = 4;
tetha0 = 0;
syms x y l

n = [h.*((cos(tetha)).^2)./sin(tetha); h.*abs(cos(tetha)); 0];
ft = ((tetha - pi/2)./sin(tetha)).^4;
Rt = [cos(tetha) -sin(tetha); sin(tetha) cos(tetha)];
zt = [cos(tetha0) -sin(tetha0); sin(tetha0) cos(tetha0)];
lt = [x;y];

integrand = @(x,y)(ft.*h.*((abs(cos(tetha)).*(x.*cos(tetha)-y.*sin(tetha)))-((cos(tetha)).^2/sin(tetha)).*(x.*sin(tetha)+y.*cos(tetha))));
PhiHat = @(a,b)(dblquad(integrand,0,a,0,b));
ezsurfc(PhiHat,[0,5,0,5])
