Usage
Returns the real part of the input array for all elements. The
general syntax for its use is
y = real(x)
where x is an n-dimensional array of numerical type. The output
is the same numerical type as the input, unless the input is complex
or dcomplex. For complex inputs, the real part is a floating
point array, so that the return type is float. For dcomplex
inputs, the real part is a double precision floating point array, so that
the return type is double. The real function does
nothing to real and integer types.
