- fast-inverse-transpose MATRIX #!optional RESULTprocedure
Efficiently inverse the transpose the unscaled MATRIX. If MATRIX has been scaled, this will produce incorrect results: inverse then transpose should be used instead. If the matrix RESULT is given, it will be modified to contain the result. If RESULT is #t, MATRIX 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, MATRIX must be an f32vector and the returned value will be an f32vector located in normal garbage collected memory.
