Using the attached data and the following code:
[TH_45, R_45, Z_45] = meshgrid(theta_45,r_45, z_45);
[X_45,Y_45] = pol2cart(TH_45, R_45);
figure;
h = axes;
p1 = patch(isosurface(X_45, Y_45, Z_45,data,500));isonormals(X_45, Y_45, Z_45,data,p1)
p1.FaceColor = 'blue';
p1.EdgeColor = 'none';
view(-23,6);
axis tight
camlight
lighting gouraud
I get the following error meassage:
Error using interp3 (line 149) Input grid is not a valid MESHGRID.
Error in isonormals (line 75) n(:,1)=interp3(x, y, z, nx, verts(:,1), verts(:,2), verts(:,3));
I can't find the solution to that issue.
