Using the code pol2cart and cart2pol, trying to prove that the rho and theta input can be retrieved back but its not giving the same values. HELP!
prompt1 = 'what is I1?';
prompt2 = 'what is I1 angle?';
RHO = input(prompt1);
THETA = input(prompt2);
[X,Y] = pol2cart(RHO,THETA)
[THETA1,RHO1] = cart2pol(X,Y)

Akintomide - you may need to provide an example of the code not working. Remember, according to pol2cart, the theta must be in radians AND the input to plo2cart is THETA first and then RHO. For example,
RHO = 42.3;
THETA = pi/4;
[X,Y] = pol2cart(THETA,RHO)
[THETA1,RHO1] = cart2pol(X,Y)
produces the expected/desired result.
