function middleElement $=$ FindMiddle$($squareArray$)$

$\%$ FindMiddle: Return the element in the center of squareArray

$\%$ Inputs: squareArray $-$ n x n input array, where n is odd

$\%$

$\%$ Outputs: selectedData $-$ center element of squareArray

$\%$ Assign elementIndex with location of middle row$/$col

$\%$ Hint: Use the size$()$ function to deterimine the dimension of squareArray

elementIndex $=0$;

$\%$ Assign middleElement with the center element of squareArray

middleElement $=0$;
