The float scalar type is now supported by the matfaust API for both CPU and GPU. Besides, the GPU features of matfaust are now compatible with CUDA 11 (in addition to CUDA 9).
Note: Matlab doesn’t support float sparse matrices, but matfaust does! Hence when you call Faust.factors on a float sparse Faust to retrieve one factor you’ll get a double sparse matrix as a copy of the float sparse matrix.
