`(m*vector-array! MATRIX VECTORS stride: [STRIDE] length: [LENGTH])`procedureDestructively multiply the array of 3 element floats

`VECTORS`by`MATRIX`.`VECTORS`may be given as an f32vector, a u8vector or a pointer. The keyword`STRIDE`specifies the number of elements between consecutive vectors, given in number of floats (which must be at least 3) when`VECTORS`is an f32vector and in bytes when`VECTORS`is a u8vector or a pointer. When`VECTORS`is given as a pointer, the keyword`LENGTH`must be provided, specifying the number of vectors in`VECTORS`.
