Find the real and imaginary parts from the given complex number. The real numbers can be generalized and extended in several different directions: The complex numbers contain solutions to all polynomial equations and hence are an algebraically closed field unlike the real numbers. Under both definitions, it can be seen that the argument of any non-zero complex number has many possible values: firstly, as a geometrical angle, it is clear that whole circle rotations do not change the point, so angles differing by an integer multiple of 2 radians (a complete circle) are the same, as reflected by figure 2 on the right. This is my code:

But in polar form, the complex numbers are represented as the combination of modulus and argument. You are likely not simple calling angle (x) but rather angle (x (y)) where y is either a scalar or an array, but with at least one element that is not a real positive integer as the error tells you.
