Hi, the code I have so far is attached, the professor wants us to use the TDMA method to solve for 100 unknowns. I was able to use the diag function to create the 100x100 matrix but I am unsure of how to create the 100x1 vectors for the variables X1-X100 and for the repeating values of "2.5,2,1.5,1 etc". Help would be greatly appreciated! Very new to coding and the textbook offfers practically no guidance.

A = what you have already constructed
d = repmat([2.5;2.0;1.5;1.0],25,1);
Then code up your TDMA.
