m- A B #!optional RESULTprocedure

Subtract matrix B from matrix A. If the matrix RESULT is given, it will be modified to contain the results of the multiplication. If RESULT is #t, A and B must be f32vectors and the returned value will be an f32vector located in non-garbage-collected memory (the memory will still be freed when there are no more references to the matrix). If RESULT is not provided, A and B must be f32vectors and the returned value will be an f32vector located in normal garbage collected memory.
