MATLAB: Converting rectangular form complex numbers into polar form

convertrectangular form

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

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

Z = 4 + j 5

You could have found this by searching right here(some one answered in 2014)...does it work for you?

x=2+3j

rho=abs(x)

theta=angle(x)

%-------------------

x=rho*exp(j*theta)

"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

Manually:

r = abs(z);
theta = atan2(imag(z),real(z));

Also...

r = abs(z);
theta = angle(z);
