In this video I show the basic use of common built-in functions to work with complex numbers in Matlab.
Arithmetic operations, magnitude, angle, conjugates.

In mathematics, the factorial of a positive integer n, denoted by n!, is the product of all positive integers less than or equal to n.
By definition, the factorial of 0 (noted 0!) is 1.
The shown code is a way of handling it in Matlab.
Online Calculator for Nominal and Effective Interest Rates:

Nominal and Effective Interest Rates are explained with an example. Formulas and full codes in Matlab are given.
To calculate the Nominal Interest Rate you need to know four parameters in advance: initial value or principal, final or future value, the number of compounding periods per year and the number of years.
To calculate the Effective Interest Rate you don’t need to know the number of compounding periods per year, but you do need the other three numbers.
In this presentation I show you how to read an electric meter. It is a very easy procedure, just like reading a clock, but there are several dials, some clockwise and some others counterclockwise.
