Function isreal - complex numbers, MATLAB in Mathematics

Assignment Help:

Function isreal - complex numbers:

The function isreal returns 1 for logical true when there is no imaginary part of the argument, or 0 for false when the argument does have an imaginary part (even if it is 0). For illustration,

>> isreal(z1)

ans =

   0

>> z5 = complex(3)

z5 =

   3

>> isreal(z5)

ans =

   0

>> isreal(3.3)

ans =

   1

 

For the variable z5, however it displays the answer as 3, it is really stored as 3 + 0i, and that is how it is exhibited in the Workspace Window. And hence, isreal returns logical false as it is stored as a complex number.
