ttest2 negative value

Hi all,

I would like to test if the mean of vector X is lesser or greater or equal to the mean of a vector Y using the statistical hypothesis Student Test with the function ttest2(). I have read in an article that the function "ttest2" can return -1 if mean(X)<mean(Y), or 0 if (mean(X)==mean(Y)) or 1 if(mean(X)>mean(Y)). However, I didn't find how to do this with ttest2 since in the official documentation, there's no negative result.

Any help please ?

Many thanks
