Details:
Comparing a matrix with a vector works fine for full and sparse matrices on
Matlab, but on Octave it gives an error for sparse matrices.
octave:1> A = [1 3; 7 5]; b = [2; 6];
octave:2> A < b
ans =
1 0
0 1
octave:3> sparse(A) < sparse(b)
error: mx_el_lt: nonconformant arguments (op1 is 2x2, op2 is 2x1)
On Matlab, however, it works fine ...
>> A = [1 3; 7 5]; b = [2; 6];
>> A < b
ans =
2x2 logical array
1 0
0 1
>> sparse(A) < sparse(b)
ans =
2x2 sparse logical array
(1,1) 1
(2,2) 1
