explain i=0; in matlab

In MATLAB, "i=0" means assigning the value 0 to the variable "i". In MATLAB, "i" can be a variable name just like any other variable and does not necessarily represent the imaginary unit (which is commonly denoted as "i" in mathematics).

For example, you can assign the value 0 to the variable "i" in MATLAB as follows:

main.m
i = 0;
7 chars
2 lines

This statement means that the variable "i" now has a value of 0, and you can use it in your MATLAB code as needed.
