linalg:cos

(linalg:cos array)

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