 Usage:  z = complex (re {, im})  
 
 Input:

  re                     n x p x d1 x ... x dn array real part of x 
                         
  im                     n x p x d1 x ... x dn array imaginary part of x 
                         
 Output:

  z                      n x p x d1 x ... x dn complex array
