I recommend you see this explanation of Stephen Cobeldick :

Learn to use MATLAB as a vector and array language. After all, that is how it is designed to be used.

If I'm understanding what you're trying to do, you're only missing parentheses.

>> n = 10;
>> p(10) = 2;
>> p(n)

p(n) = 

    2

You can also assign values in a similar manner.

>> n = 10;
>> p(n) = 2;
>> p(10)

p(10) = 

    2

Put if 0 it fails ...

[Bob Thompson]

Yes, because the value inside the parentheses is referencing a position within an array. You cannot call a 0 placement, because a 0 position doesn't make sense.
