MATLAB Create a new $.$m script in your editor and save it with the name exercise$2.$m

$2.$

Write in your script editor the $3-$by$-3$ matrix A

$3.$

Write in your script editor the column vector b

$4.$

Write the command to invert the matrix A and compute the solution vector $($see the attached example$2\_2.$m for guidance$)$

$5.$

Use basic indexing $($see Lecture #$2$ notes$)$ to define the scalars x$,$ y$,$ and z as the first, second, and third elements of the solution vector $$

$6.$ Compute the scalar $=3$log$+2$cos$(2)+5($sin$)2$

Make sure that your script runs before uploading it on Brightspace
