difference between two double vector?

Hi. I am new in matlab so if you help me I will be grateful. I do not know the difference between these two data:

p=[0.0476 0.1429 0.0952 0.0476 0.0476 0.1429 0.0476 0.0476 0.0952 0.0952 0.0476 ]

and

p =
  Columns 1 through 11
    0.0476    0.1429    0.0952    0.0476    0.0476    0.1429    0.0476    0.0476    0.0952    0.0952    0.0476

When I use the first data in a function the answer is correct but the second one is not. How can I save the second one like the first one and then use it?

They're the same. The first one is just the code - how the variable is assigned. It's how it looks in the editor window. If you execute that code, it will show up like you have in the second section. That's just how it looks in the command window and will echo there if you don't put a semicolon on the end of the line. That is not something that you'd actually execute as part of your script - it's just the displayed output of an assignment command.

Beyond that, I'm not really sure what you want to do. You obviously already have p because you displayed it in the command window, so just start using it. Why do you think you need to do anything other than use "p"???

i want to use it in dict=huffmandict(alpha,prob) function.and p is the probality.actually i dont have the first data i just use it to try the code and the second data is data that i extract from image and use it to create huffman dictionary.

So go ahead and us p. There should be no problem.

but the answer is not correct.i know both of them are the same but have different result in function

At the command prompt give the command

format long g

and then display p (the right one) again. You will find that the values are not exactly the same as in your code: the values only round to be the same. You can then check further by subtracting the p from your code from the right p and showing the difference between them.

thanks now i know where is the problem and solve it
