I have the following expression in polar form 700 angle of 8.11 ..... I want to express this number in matlab. How can I express it as a single number in either polar or rectangular mode?

There is no MATLAB notation for polar form. Some languages have notations such as 700+<8.11 but MATLAB does not.
For radius R (such as 700) and angle A (such as 8.11*pi/180) then the complex representation is
R*(cos(A) + 1i*abs(sin(A)))
This might not work for negative angles, possibly.

Thanks alot, it worked fine. As far as negative angles, I just expressed them in positive to avoid mistakes.
