'Pends.

You mean just at the display or in the actual data?

If it's for the display, there isn't an "integer" format option; 'short' or maybe 'bank' (2 decimals F format) is about as fine as it gets unless you write the output with formatted io like

num2str(x,0)

If you mean you want integral valued values for the variable r itself, then

 r=round(a + (b-a)*rand(N));

does the trick.

Although can save a step by using randi instead

 r=randi([a,b],N);
