Converting polar form complex numbers into rectangular form

I am having trouble converting polar form complex numbers into rectangular form by writing a MATLAB script file.

I'm not fimular with MATLAB keywords but need to use this to prove my answers.

Z = 0.5 angle( pi / 4 )

or

Z = 0.5 angle( - 45 degrees )

Create the following two functions in MATLAB in order to easily convert between complex rectangular and polar forms. Test the functions by confirming that 3 + 5j  5.859

"Converting polar form complex numbers into rectangular form"

z=0.5;theta=pi/4;
[X,Y]=pol2cart(theta,z)

Result:

X =
    0.3536
Y =
    0.3536
