%Please help me to find Tx and Tc

This is called a circulant matrix. I have written a function that can be found in the File Exchange:
A = [100 125 300 400]
B = circulant(A,-1)
tf = flipud(tril(true(size(B))))
C = B(tf)

Sorry, lame joke. But I did not understand your question. Can you rephrase it?
