nlcpy.real

nlcpy.real(val)

Returns the real part of the complex argument.

Parameters

valarray_like: Input arrays or scalars.

Returns

outndarray: The real 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. If val is a scalar, this function returns the result as a 0-dimention array.

imag: Returns the imaginary part of the complex argument.
angle: Returns the angle of the complex argument.

Examples

>>> import nlcpy as vp
>>> a = vp.array([1+2j, 3+4j, 5+6j])
>>> a.real
array([1., 3., 5.])
>>> a.real = 9
>>> a
array([9.+2.j, 9.+4.j, 9.+6.j])
>>> a.real = vp.array([9, 8, 7])
>>> a
array([9.+2.j, 8.+4.j, 7.+6.j])
>>> vp.real(1 + 1j)
array(1.)
