Code has already been provided to define a function named matrixFun that accepts an input variable A that is a matrix with $M$ rows and $N$ columns of numbers. Add commands

to the function to perform the operations described below and assign the results to the indicated output variable names.

Create a new $2N$ matrix, $B,$ that consists of the first and last rows of $A.$

Create a new $22$ matrix, $C,$ that consists of the elements at the four corners of $A.$

Create a new $(M-1)(N-1)$ matrix, $D,$ that consists of the second through last columns in the second through last rows of $A.$

Solve this problem using only vectorized code with no loops. Note the variable $A$ is defined as a function input. Do not overwrite the value in your code.
