replace.m (439B)

      1 % Replace.m    Replaces the elements in X taking value V with value v2
      2 %    Note, v1 is a matrix of zeros and ones, and
      3 %          v2 is a scalar; or v2 has same dimension as x -- choose elements.
      4 %
      5 %	To replace all 1's with 0's:  replace(x,x==1,0)
      6 %	To replace all NaN's with 0's: replace (x,isnan(x),0)
