Optimization of Functions of Complex Variables
8.1 Complex Numbers
MATLAB implements a simple way to work with complex numbers in binary form a+bi or a+bj, representing the imaginary unit by means of the symbol i or j. Note that it is not necessary to include the product symbol (asterisk) before the imaginary unit, but if it is included, everything still works correctly. It is important, however, that spaces are not introduced between the imaginary unit i and its coefficient.
Complex numbers can have symbolic or numeric real or imaginary parts. Operations are carried out with a precision that is set by the command format. Thus, it is ...
