For

odd, consider the

where the diagonals contain no zero values.

The center element is

<sub>k

k</sub>. Find a formula for

Develop a function

that solves the system

The function must only use the nonzero values {ai},{bi}. Output an error message and terminate under the following conditions:

●

is even.

●

and

do not both have n elements.

● The diagonals do not share a common center.

Develop a function

that builds an
-matrix. Let

length

Generate an error message if

is even or length

Develop a function testxmatsolve
that times the execution of

builds the matrix

and times the execution of the MATLAB command

Let

and call buildxmat. Comment on the results.
