Details:
I would like to request thoughts on implementing sparse single matrices. The
main reason would be so that addition and multiply can be performed on
non-sparse single matrices and vectors. E.g.
A = sparse(randn(10));
x = randn(10,1,"single");
b = A*x;
error: binary operator '*' not implemented for 'sparse matrix' by 'float
matrix' operations
I have an application that uses a sparse matrix multiply in amongst other
operations (FFT, dense multiplies, etc.) and it all has to be done in doubles
because of the sparse operator. The data comes in as 16-bit ints so single
precision is plenty.
