I have imported a .dat file into matlab, with data for a x axis and for the y axis. I want to specify a region on the x-axis (like a<x<b) and then I want the corresponding y values saved. I understand how to get the x values but not how to get the corresponding y values.

mask = a <= x & x <= b;
selected_x = x(mask);
selected_y = y(mask);
