Attempt to execute SCRIPT surfnorm as a function:

Hi, I'm attempting to use the surfnorm function to produce a set of perpendicular vectors to a hemisphere.

I have used this function before without problem but I have been having some issues. Here is the code

R=22; phi=linspace(0,pi,50); theta=linspace(-pi/2,pi/2,50);
[phi,theta]=meshgrid(phi,theta);
X=R*sin(phi).*cos(theta); Y=R*sin(phi).*sin(theta); Z=R*cos(phi);
[Nx,Ny,Nz]=surfnorm(X,Y,Z);
quiver3(X,Y,Z,Nx,Ny,Nz)

As stated in the title I get the error:"Attempt to execute SCRIPT surfnorm as a function"

even when I run the example code given on the website:

[x,y,z] = cylinder(1:10);
figure
surfnorm(x,y,z)
axis([-12 12 -12 12 -0.1 1])

I get the same error.

Any help or comments would be appreciated, thanks. John

Most likely there is another file named surfnorm that shadows the proper file. Run

which surfnorm -all

to find out

You are correct - found the file and deleted it. Thanks for your help.
