Follow-up Comment #11, bug #45219 (group octave):

Test Environment: Octave (version:11.0.92)
Obviously, it was resolved much earlier.
Test Results:

The original test case from 2015 was run:


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

% Test 1: Dense matrix addition (original working case - for reference)
a = t1 + t2
% Result: Success - 6x3 complex dense matrix

% Test 2: Dense matrix bsxfun (original working case - for reference)
b = bsxfun(@plus, t1, t2)
% Result: Success - 6x3 complex dense matrix

% Test 3: Sparse matrix addition (original failing case)
c = s1 + s2
% Result: SUCCESS - Returns 6x3 sparse complex matrix (100% filled)
% No "nonconformant arguments" error as originally reported

% Test 4: Sparse matrix bsxfun (original failing case)
d = bsxfun(@plus, s1, s2)
% Result: SUCCESS - Returns 6x3 sparse complex matrix (100% filled)
% No "concatenation operator not implemented" error as originally reported

Verification:

All operations complete without errors

The results from sparse operations (c and d) correctly match their dense
counterparts (a and b)

Broadcasting works correctly with mixed real/complex sparse matrices

Both the + operator and bsxfun produce identical, correct results

Conclusion:

This bug can be closed as FIXED.
