Matlab letter "h" question

Can somebody explain me why is there "h" at the beginning of the numbers?

function w = hanning(n)
load('han.mat');
switch n
    case 2220
        w = h6000;
    case 2960
        w = h8000;
    case 4079
        w = h11025;
    case 5920
        w = h16000;
    case 8159
        w = h22050;
    case 11840
        w = h32000;
    case 16317
        w = h44100;
end

The letter "h" is there because you cannot name a matlab variable with just digits.

Answer 2

[Walter Roberson]

Those are not numbers, those are variables that have been loaded from han.mat . I have no idea at the moment what is in the variables.

http://cnx.org/content/m14233/latest/han.mat that's the file. I want to implement something similar in Java but I am not really sure what all this variables mean.

Answer 4

[Rambo]

that's clear but when I open han.mat file for each variable it has so many values. I have no idea what these values mean. It says it is a function for producing a hanning window. And how it is possible to store so many numbers in a one variable unless it is not a variable but array?

An array is just a variable with a lot of components. For example, you could type

h1 = 1:10;

and this creates a vector h1. This is a variable because you can change any component of it:

h1(1) = 0;

or add to it:

h1 = [h1 11];

I have arbitrarily added the number 1 to the name to show that it can be done.
