Memory requirements

The memory requirements of the various programs can be expressed in terms of the bytes of memory required per pixel of the microstructure. The following numbers assume that double precision (REAL*8 and COMPLEX*16) is used. Only the memory requirements for arrays that are of the system size are counted. Variables like dk, phasemod, and sigma are ignored in this count, since their memory requirements scale with the number of phases, and this number is usually of order one.
