sparse half-precision matrices

I'm experimenting with solving linear systems in half precision using matlab. I'm using the somewhat recently introduced 'half' data type. I can convert full matrices to half precision no problem. But if I then try to call sparse(M) I get an error saying "Undefined function 'sparse' for input arguments of type 'half'".

Is there a way I can define this function myself? I don't know too much about MATLAB so I'm unsure of where to start.

The sparse format in MATLAB only supports double and logical data types. To use any other data type you would have to write all of the underlying code yourself (a very big undertaking).

Oh, I see. Thanks for your help.
