Write a fortran 90 code for solving Ax = b, (where A consists of Reals of a n*n and b consists of reals of n) if A is TRIDIAGONAL. You MUST incorporate PIVOTING. Your storage for A MUST be an array of size 4*n (4 rows, n columns). Test your code and produce output for Ax = b with a = 1/(2n-i-j+1) n=6, b=1 2 3 4 5 6 a copy of the code and OUTPUT must be produced.
1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased.
program can be on any system as long as it is in fortran 90 and the program produces what is asked for.
## Deadline information
please include comments to explain steps. also critical that there is an output and it is the correct one.
