I have uploaded a txt file containing a large number of rows, and five columns. The first 4 columns are values collected from instrumentation in a test facility, and my 5th column is filled with time values when the data was collected. I can place the data into an array, but I would like to reduce the data depending on the time value. For example, I would like data from all four of my instrumentation readings between 8 seconds and 10 seconds.

what don't you index your array by the last column?
for example, myData is the array you mentioned with five columns, and suppose your last column is in unit second. Try:
subSet = myData(myData(:, 5) >= 8 & myData(:, 5) < 10, :);
