mars.tensor.iscomplex

mars.tensor.iscomplex(x, **kwargs)

Returns a bool tensor, where True if input element is complex.

What is tested is whether the input has a non-zero imaginary part, not if the input type is complex.

Parameters

x (array_like) – Input tensor.

Returns

out – Output tensor.

Return type

Tensor of bools

>>> import mars.tensor as mt

>>> mt.iscomplex([1+1j, 1+0j, 4.5, 3, 2, 2j]).execute()
array([ True, False, False, False, False,  True])
