Complex Number Representation in Matlab

Click For Summary
SUMMARY

The discussion focuses on converting complex numbers from Cartesian to polar form in Matlab. The user seeks a method to convert the complex number z = 0.1602932442 + 0.8277219859*j into its polar representation. The solution involves using the built-in functions abs(z) for magnitude and angle(z) for phase. The output should be formatted as 0.8431<79.04 deg, demonstrating the conversion without manual calculations.

PREREQUISITES

Hey Everyone,

I cannot seem to find an way in Matlab to convert a number which has a real and imaginary part in cartesian form into polar form and then express the polar representation on the output.

Ex.

Convert
z=0.1602932442+0.8277219859*j

Into

0.8431<79.04 deg (without using my calc.)

Thanks

Use abs(z) for the magnitude and angle(z) for the phase of z. Type "help abs" or "help angle" at the prompt for more help on these functions.
