Can someone explain please what the T in means in this line of code T = [40 T 200]; Below is the reference code.
a = [ 2.04 -1 0 0; -1 2.04 -1 0; 0 -1 2.04 -1; 0 0 -1 2.04;] b = [40.8 0.8 0.8 200.8]'; T = (a \ b)'
T = [40 T 200]; x = [0: 2 : 10]; xanal = [ 0: 10]; TT = @ (x) 73.4523*exp(0.1*x) - 53.4523*... exp(-0.1*x) + 20; Tanal = TT(xanal); plot(x, T, 'o', xanal, Tanal)

Yeah it's from the matlab book Applied Numerical Methods with Matlab Case Study 9.5. I just got rid of the double T's and it worked.

The first T = (a/b)'
It is the solution of equation which is solved and transposed to make the next step easier ,and then
The second T = [20 T 200] which has the initial point and the end point added to it. That’s what it actually means
