Please use Matlab and give me a code that can be executed directly and correctly,thanks!

1) Use the improved algorithm for solving tri-diagonal set of simultaneous equations to write MATLAB code to solve the following equations: 3x1+2x2x1+3x2+2x3x2+3x3+2x4x3+3x4+2x5x4+3x5=8=1=5=7=6 Printout the computer program and computational results. Follow your computer program given in part (a), use hand calculations to check your computational results
