Look at the find() function. You can use logical operators like < , > , and = . Just try some things and see what happens.

Why not just testing it ?
Many big inventions would not have been possible without the curiosity of the people engaged in the subject.

A further hint: "30<=xi<=50" might be misleading, because Matlab processes such terms from right to left. Therefore you need to connect the two relations by an and():
30 <= x & x <= 50
