How to solve?Give me the code that can have direct answer. I have asked fourth. Nobody correctly answer me.

Use the improved algorithm for solving tri-diagonal set of simultaneous equations to write a 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. function x= triDiagonalSolver (a,b,c,d) Error: Function definition not supported in this context. Create functions in code file. function x=triDiagonalSolver(a,b,c,d) n= length(d); \% Forward elimination for k=2:n factor =a(k1)/b(k1); b(k)=b(k) - factor * c(k1); d(k)=d(k) - factor * d(k1); end \% Backward substitution x=zeros(size(d)); x(n)=d(n)/b(n); for k=n1:1:1 x(k)=(d(k)c(k)x(k+1))/b(k); end end Main program:- \% Coefficients of the tri-diagonal system a=[1;1;1;1]; b =[3;3;3;3;3]; c=[2;2;2;2]; d=[8;1;5;7;6]; \% Solve the tri-diagonal system x=triDiagonaISolver(a,b,c,d); \% Display the results disp('Solution to the system of equations:'); disp(x)
