Compute the facets to draw a complex function.
[xr,yr,zr,xi,yi,zi] = scidemo_cmplxfacets (R,e,TypeDomain,TypeCut,n,StrFunc)
length of half a side of the square or radius of the disk
thin layer to avoid the branch(es) cut(s)
a 1-by-1 matrix of strings, "Square" or "Disk"
a 1-by-1 matrix of strings, "Ox" or "Oy"
a scalar (for "Square") or a 2-vector = [ntheta, nr] (for "Disk") for discretization
a 1-by-1 matrix of strings, the string which names the complex function (this is because primitive don't pass as function argument)
a m-ny-n matrix of doubles, real and imaginary parts of X,Y and Z values
A function to compute the facets for drawing a complex function on a square or a disk with branch(es) cut(s) on Ox or Oy
