Question

In my function I’d create a variable that will contain simply one number. How do I initialize it?I have to initialize it to 0 value or I can initialize it simply putting in function var;

Answer 1

In Matlab, variables are initialized dynamically. There is no C++ or Java equivalent of memory allocation versus initialization.

For example:

C code:

 int x; // Allocate memory on the stack for integer.
 x = 5; // Assign the value 5

Matlab code:

 x = 5;  %# Allocate memory and assign the value 5

You can’t break this in two parts in the following way:

 x; %# SYNTAX ERROR! x is not defined yet.
 x = 5;

Also, I am not sure whether you meant that var is some kind of a keyword, but in case you think it is – you’re mistaken.
