MATLAB: How to find all (latitude,longitude) that lie inside a rectangle with known x-y coordinates on the plot

Question

I have a file that contains the latitude and longitude, of several points over a region.

How do I iterate through my lat-long file, to return all the (lat,lon) that lies within some x-y limit on my plot? The problem being that the coordinates are floating points.

Any help is highly appreciated!

doc inpolygon .

inpolygon gives you indices of points(x,y) that lie inside the boundary points/ closed region (xb,yb). With these indices, you can select your points which lie inside the given closed region.
