Flopscope Context

Return imaginary part of complex array. Component extraction -- a view (or constant-fill for real input), no arithmetic -- so it is free.

Parameters

val:array_like

Input array.

Returns

out:ndarray or scalar

The imaginary component of the complex argument. If val is real, the type of val is used for the output. If val has complex elements, the returned type is float.
