YM11 Generate a random sparse matrix

These subroutines generate an m by n random sparse matrix with user-specified options such as structural nonsingularity and bandedness. The matrix is held in a packed form in a standard sparse matrix format, and there is an option to write it to a file in Rutherford Boeing format (Report RAL-TR-97-031).
