m01edf is designed to be used typically in conjunction with the ranking routines
m01daf,
m01dbf,
m01dcf,
m01def,
m01dff,
m01djf,
m01dkf and
m01dzf. After one of those routines has been called to determine a vector of ranks,
m01edf can be called to rearrange a vector of complex numbers into the rank order. If the vector of ranks has been generated in some other way, then
m01zbf should be called to check its validity before
m01edf is called.

This example reads a matrix of complex numbers and rearranges its rows so that the elements in the
th column are in ascending order of modulus. To do this, the program first calls
m01daf to rank the moduli of the elements in the
th column, and then calls
m01edf to rearrange each column into the order specified by the ranks. The value of
is read from the datafile.
