MATLAB: Confused about num2str function

for loopnum2strplottittle

I have looked at the online help the very first line reads:
 "The num2str function converts numbers to their string representations. This function is useful for labeling and titling plots with numeric values."
This is exactly what I want to use it for, I have to plot a function every time a for loop reiterates itself And I want to change the title of each successive plot to "plot1" "plot2" "plot3" and so on….
But I have not found a way to do this.

Hi, here is an example:
 for nn = 1:10,
 plot(randn(100,1)); 
 title(['plot' num2str(nn)]); 
 pause(0.5); 
 end
