Develop a Matlab function for the Gauss$-$Seidel method using the provided pseudocode as a guide. For this problem, assume lambda $=1.$Test the program using the system below. Be sure to output the solution. A $=[3-0\mathrm{.}1-0\mathrm{.}2$ ; $0\mathrm{.}17-0\mathrm{.}3$ ; $0\mathrm{.}3-0\mathrm{.}210],$ B $=[7\mathrm{.}85$ ; $-19\mathrm{.}3$ ; $71\mathrm{.}4]$
