private

Writes a distributed array to a file (master, complex).

Parameters

mygrid	BLACS descriptor
fd	File descriptor of an opened file.
desc	Descriptor of the distributed matrix
mtxloc	Local portion of the distributed matrix
rowwise	If .true. matrix is dumped rowwise otherwise columnwise
elemformat	Formatting of one element (e.g. "(E23.15)"). If present matrix will be written formatted, otherwise the matrix is written unformatted. The file descriptor must accordingly belong to a formatted or an unformatted file! The formatting string must contain the delimiting parantheses.
