`m*s``A``S``#!optional``RESULT`procedureMultiply matrix

`A`by scalar`S`. If the matrix`RESULT`is given, it will be modified to contain the results of the multiplication. If`RESULT`is`#t`,`A`must be an f32vector 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`must be an f32vector and the returned value will be an f32vector located in normal garbage collected memory.
