linalg:less

(linalg:less a b)

Returns the elementwise a < b comparison as a 0.0/1.0 mask (numpy's <, which produces a boolean array); either operand may be a scalar, and arrays broadcast by numpy's rules exactly as linalg:add describes. Multiply by the mask where numpy would boolean-index. The siblings are linalg:less-equal, linalg:greater, linalg:greater-equal and linalg:equal.
