Use this function header in your function file:

function $[$min$\_$matrix,max$\_$matrix$]=$min$\_$max$\_$matrix $(A)$

where $A$ is the matrix input, min$\_$matrix is the minimum matrix element output, and max$\_$matrix is the maximum matrix element output.

Do not use any Matlab built$-$in functions in your function; your implementation should instead utilize a double for loop to loop over all the elements in the rows and columns of a matrix.

Also think about how you are going to determine how many rows and columns the input matrix has; your function should be able to figure out the size of the input matrix, rather than have a specific row and column count hard$-$coded.

Test your implementation on the following matrix by writing a script and passing this matrix to your min$\_$max$\_$matrix function:

After defining matrix B given above, call your function within your script like so:

$[$out$1,$out$2]=$min$\_$max$\_$matrix$($B$)$

and check that results out$1$ and out$2$ return the correct results.

Additionally, make up another matrix, called, say, C$,$ and test your implementation out with your own matrix C; e$.$g$.,$ generate one at random using either rand or randn $($see help rand or help randn for details$)$; set the random number generator seed to a specific value to get repeatable results if that is important to you $[$e$.$g$.,$ rng$(1)$ sets the random number generator seed to $1$ so that every time you do clear all, the random number generator resets to the same state and the same random values are regenerated for you$].$ Do all of the testing on your own matrix within the same script used above $($resist the temptation to do everything at the command line$).$
