CMPLXMULT-Multiply two complex structures

Description:

CMPLXMULT multiplies two complex data structures. These may have any shape and size, so long as they are both the same. A 'complex data structure' here means a structure containing a .Z.REAL, a .Z.IMAGINARY and a .Z.DATA array, all with dimensions that factorise easily so that FFTs can be applied to them.

Parameters:

CDATA

The first complex data to be multiplied.

CDATA1

The second complex data to be multiplied.

OUTPUT

The name of the resulting structure. This can be the same as CDATA, in which case no new structure is created. Otherwise, OUTPUT will be a new file, with the same structure as CDATA.

 This routine services the Figaro complex structure arithmetic
 routines CMPLXADD, CMPLXSUB, CMPLXDIV, and CMPLXMULT.  These
 commands operate on two complex structures, performing element
 by element arithmetic to produce a new structure.  The complex
 structures may be of any dimensions, so long as they match.

 Command parameters -

 CDATA    (Character) The name of the first complex structure.
 CDATA1   (Character) The name of the second complex structure.
 OUTPUT   (Character) The name of the resulting structure.

 Command keywords - None
