I mean, i have to check if a segment (who changes in time) is entirely inside a polygon or not. Is there any function in Matlab who does that?

you can use inpolygon function to check if a point in a polygon.

Use a for loop. I doubt you have "a lot" of points. How many? Hundreds of millions? If you have just a few tens of thousands, it will be very fast. If you have millions of points, then you might consider image processing techniques instead.
