Help with regress syntax

Hallo I am trying to apply the regress function in a simple x,y scatter plot but for some reason I can't find the exact syntax that will give the p-value.How is the correct syntax in order to take the p-value as an output?

[Panos Ale]

To be more specific, Ι can't understand how the input variables should be. How can I form my values in x axis into the X input?And is input y the values in y axis?

By reading the help for regress ...

help regress

{stuff snipped away}

[B,BINT,R,RINT,STATS] = regress(Y,X) returns a vector STATS containing, in
  the following order, the R-square statistic, the F statistic and p value
  for the full model, and an estimate of the error variance.

So it looks like

STATS(3)

might be of interest to you.

I read it but I still have trouble writing the correct command...

You are not providing sufficient detail. How exactly are you having trouble? If one were to troll, one could answer: "learn to write", "check your keyboard".

Probably more helpful would be saying: Y and X are probably not what regress expects them to be. Impossible to say with the information you have provided.

Actually the troll answers would be realistic in my case though not very helpful. I think you are right, Ι can't understand how the input variables should be. How can I form my values in x axis into the X input?And is input y the values in y axis?

Sorry for the misunderstanding, I am an amateur in Matlab!

You can start by trying out the examples provided in the documentation and comparing to what you actually have (and which we can't see so we can't help you there).

Otherwise provide data reproducing your problem.
