I suggest you first make sure your variables are set correctly. Try:
It might be that your source file contains hidden formatting characters which will not show in the copy here but may interrupt the reading of your file. It never hurts to ascertain each step separately.
The next thing is to apply the printed cut-commands manually one by one and see if they work as expected. One problem might be that you need to specify a field-delimiter (see option "-d" of "cut") to parse the file "matrix" correctly (not all cut-versions will understand tabs instead of spaces, for instance).
Btw: in scripts i would - just to be 1000% sure - always write "${var}" instead of "$var". In most cases the latter works the same, but in some combinations (within complex statements) the former might avoid ambiguity. Therefore:
I need to read a file (a list) and assign the value to a variable (for each line), I'm looping until the end of the file. My problem is, I want to assign 2 separate variables from the list. The process I'm using is:
