Details:

Hi,

The slices of diagonal matrices (also diagonal matrices) are not automatically
broadcasted.

Example


A = eye(3);  # Diagonal Matrix
v = A(1,:);  # Single row Diagonal Matrix
B = rand(3); # Full Matrix

# Test
B - [1 0 0]; # No problem

B - v;
error: operator +: nonconformant arguments (op1 is 3x3, op2 is 1x3)
