Suppose that $A$ is a $1010$ matrix, and we want to extract a submatrix consisting of rows $2$ to $7,$ and columns $1$

to $5$ of $A.$ What single Matlab command $($using $10$ characters or less$)$ could accomplish this? $($Assume that the

matrix A has already been defined in Matlab, and has been called A$.)$

Note that for this question you should test your answer to see if it works. For this purpose it would be useful to

have a $1010$ matrix sitting around somewhere. There are several ways to quickly generate matrices in Matlab.

For example, rand $(10)$ will produce a $1010$ matrix whose entries are random numbers between $0$ and $1.$

magic $(10)$ will produce a $1010$ magic square matrix.
