Complex Numbers
Real and imaginary components, phase angles
In MATLAB®, i
and 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.
