A way to sample outputs in every 1 us (micro second)

Hi all,

I have measurement data form Logic Analyzer. I measured my chip using 1 Mhz clock, and saved data to a csv file. I want to have one output in every 1us since my clock is 1Mhz. However, the data was not measured in every 1ns. I do understand a Logic Analyzer is smart so it reduces a step size in a transition, and the logic analyzer increase a step size when outputs do not change in long time. However, it makes me crazy to collect and analyze data. How do I solve this issue?

The first column shows time, and the second column shows value. When it transits from 0 to 1. Time step is smaller than 1us since a logic analyzer tried to measure it precisely. When there are sequential ones, it increases a step size to 2us or more. I just want to sample one data in every 1us. I would appreciate you help me. Thank you in advance.

You can use interp1 function

I've tried to do interpolation using interp1, but I couldn't get what I want to do. Could you please explain more?
