linalg:atan

(linalg:atan array)

Returns a fresh array of the same shape with the arc tangent applied to every element (numpy's np.arctan) -- equivalent to (linalg:emap #'atan array), but as a named function it is accelerated under --simd. Like atan itself, the WASM backends compute it with a software approximation whose low-order digits can differ from the interpreter's and the JVM's.
