Can anyone tell me why the following keeps burning my CPU without ever producing the desired plot?
f[x_, y_] := If[Sqrt[x^2 + y^2] < 1, 1, 0];
test[t_, z_] := N[Convolve[f[x, y], f[x, y], {x, y}, {t, z}]];
Plot3D[test[t, z], {t, -5, 5}, {z, -5, 5}];
Thanks!
f[x_, y_] := HeavisidePi[Sqrt[x^2 + y^2]/2]
.) $\endgroup$
