3- This question deals with creating Matlab functions and making function calls. Write a Matlab function and call it MyPower to do the following: A- Create the function (this question may take some time -do your research.) Given the complex current and complex voltage, the function calculates the real power, reactive power, the complex power and the power factor. ar ) Save the function B- Function Call Write a Matlab code to do the following steps: a- b- c make the function call to a function you developed to perform the calculations ddisplay the returned data (clearly) Use correct units C-

Explanation / Answer

Matlab program:

prompt1 = 'real part of voltage = ';

prompt2 = 'Imaginary part of voltage = ';

prompt3 = 'real part of current = ';

prompt4 = 'Imaginary part of current = ';

Vreal = input(prompt1);

Vimg = input(prompt2);

Ireal = input(prompt3);

Iimg = input(prompt4);

V = complex(Vreal,Vimg);

I = complex(Ireal,Iimg);

S = V*I;

fprintf(' ');

fprintf('RESULTS: ');

fprintf('Voltage = %d + j %d ',Vreal,Vimg);

fprintf('Current = %d + j %d ',Ireal,Iimg);

fprintf('S = Apparent power = %d + j %d ',real(S),imag(S));

fprintf('P = True power = %d ',real(S));

fprintf('Q = Reactive power = %d ',imag(S));
