Z = R.*exp(1i*theta)
where:
R = abs(Z)% magnitude
theta = angle(Z) % angle

Hello !!
Lets say r is the amplitude θ is the angle .
Thus the complex number formed shall be = rcosθ+rsinθi .
Real Part = r*cosθ ,
Imaginary Part = r*sinθ
Here i = iota ( complex number imaginary part operator)
I hope it will help future readers
