Using the text command, how can I display a string genrated from sprintf and a string in one line?

I want to display the p value of a ttest on a graph that I have constructed. The label has to be in the format "p = XXXX" where XXXX is the p value. I used the ttest2 command to calculate the p value which I saved under the variable p_num. The command I am currently using is:
text(mean(xlim),max(ylim),['p =',p_num])
However this is not working. How can I get this to be displayed in the proper format on the graph?

What does "this is not working" actually mean? Do you get any text at all? Does it display the wrong text? Did it blow up your computer? We do try to read minds, but your explanation is better.

text(mean(xlim),max(ylim),sprintf('p = %4d',p_num))
If you need the leading 0's printed then
text(mean(xlim),max(ylim),sprintf('p = %04d',p_num))

You don't need the intermediate string. Try this:
[h,pvl] = ttest2(Apm, Abm);
text(mean(xlim), max(ylim), sprintf('p = %.4f', pvl))
