[Octave-bug-tracker] [bug #41441] Broadcasting does not behave properly on sparse matrices

[Michael C. Grant]

Follow-up Comment #3, bug #41441 (project octave):

As I just discovered in my near-duplicate report #45219, one key factor is
that combinations of one real and one complex sparse matrix fail.

t1 = randn(6,3)+1j*randn(6,3);
t2 = randn(6,1);
s1 = sparse(t1);
s2 = sparse(t2);


These work fine:

t1 + t2
bsxfun( @plus, t1, t2 )


These do not:

>> s1 + s2
error: operator +: nonconformant arguments (op1 is 6x3, op2 is 6x1)
>> bsxfun(@plus,s1,s2)
error: concatenation operator not implemented for '<unknown type>' by 'sparse
complex matrix' operations
-verbatim+
