How do I extract data between a range in an XY array

Question

I've been using MATLAB for a while but can't seem to find an efficient way of selecting XY data between a range.

I have a large physical data set imported which is an array of XY data points, I've tried to fake a section below:

dummyXYArray = [transpose([0:1:10]) rand(11,1)];

How do I return a similarly formed array with only data between 2<x_desired<7

My slow way requires tons of steps:

xDataDummyXYArray = dummyXYArray(:,1);

yDataDummyXYArray = dummyXYArray(:,2);

clippingArray = xDataDummyXYArray>2 & xDataDummyXYArray<7;

clippedArray = [xDataDummyXYArray(clippingArray) yDataDummyXYArray(clippingArray)]

This would be my approach:

dummyXYArray = [transpose([0:1:10]) rand(11,1)];
clipped_array = dummyXYArray((dummyXYArray(:,1) > 2) & (dummyXYArray(:,1) < 7), :)
