c     -----------------------------------------
c     -----------   EXAMPLE   -----------------
c     inputs:  ch, a,b and c; ia,ib and mc,nc
c     ch=character, a=integer, b=real and c=double
c     ia,ib and [mc,nc] are the dimensions of a,b and c resp.
c     outputs: a,b,c,d
c     if ch='mul'   a,b and c = 2 * (a,b and c)
c     and d of same dimensions as c with
c     d(i,j)=(i+j)*c(i,j)

c     d(i,j)=(i+j)+c(i,j)
c     w is a working array of size [mc,nc]
