MATLAB: Size of surfnorm vectors

surfnorm

how can I introduce a max length to the vectors plotted by surfnorm or at least scale them?, I cant finde the rigth documentation to do it, thanks.

With normalizing:

[nx, ny, nz] = surfnorm(x, y, z);
L = sqrt(nx.^2 + ny.^2 + nz.^2);
quiver3( x, y, z, nx./L, ny./L, nz./L )

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

which surfnorm -all

to find out

You can specify the x- and y-vector to a scale of your own choice instead of plotting it at it's index:

x=linspace(0,25,25); 
y=linspace(0,25,25);
h = meshgrid(V);
surf(x,y,h);
