Summary: Mixed data type operations not supported with sparse
matrices
Project: GNU Octave
Submitted by: nir_krakauer
Submitted on: Mon 14 May 2012 02:33:23 AM GMT
Category: Interpreter
Severity: 3 - Normal
Priority: 5 - Normal

Open/Closed: Open
Discussion Lock: Any
Release: 3.6.1
Operating System: GNU/Linux
_______________________________________________________
Details:
Mixed operations involving sparse matrices and non-double arrays or scalars
currently return errors:
speye(2) + uint32(3)
error: binary operator `+' not implemented for `sparse matrix' by `uint32
scalar' operations
speye(2) * eye(2, "single")
error: binary operator `*' not implemented for `sparse matrix' by `float
matrix' operations
It would be useful for such operations to give sensible results, if necessary
even by automatically promoting non-double arguments to double, as in
