A pentadiagonal system with a bandwidth of five can be expressed generally as figh e2 f2 82 h₂ dz ez f3 83 h3 x1 " x2 12 X3 13 . d-en-1 fn-1 8n-1 X-1 rn-1 dn en fn Develop a program to efficiently solve such systems without pivoting in a similar fashion to the algorithm used for tridiagonal matrices in Sec. 11.1.1. Test it for the following case: 8 -2 -1 0 0 -2 9 -4 -1 0 X2 2 -3 7 -1 -2 X3 0 00 -4 -2 12 -5 X4 1 0-7 -3 15 5
