j represent the basic imaginary unit. You can use them to create complex numbers such as
2i+5. You can also determine the real and imaginary parts of complex numbers and compute other common values such as phase and angle.

|Create complex array|
|Sort complex numbers into complex conjugate pairs|
|Imaginary part of complex number|
|Determine whether array uses complex storage|
|Real part of complex number|
|Sign function (signum function)|
|Shift phase angles|
Plot the imaginary part versus the real part of a complex vector.
