Use the function ttest2 from matlab statistics toolbox.

That depends on your experimental design. If you have an unpaired design (intervention on one group and not on another) use ttest2. If you have a paired design (before an after an intervention on the same group), use ttest.
Of course this requires that your data are normally distributed and meet the other assumptions of the t-test for both groups. If they do not, or you do not know the distribution, use the ranksum and signrank tests, respectively for unpaired or paired data.
