Type the appropriate Matlab commands to do the following operations and assign the results to the indicated output variable names:

Create a random row vector of $100$ uniformly distributed pseudorandom integers between $-30$ and $30.$ Assign this to the variable A$.$ Check out the following link from Matlab help for more information on randi. Matlab Documentation is a great place to get help and learn how to use built$-$in functions in different ways.

Create a second row vector $B$ that consists of only the negative numbers in $A$ in the same order in which they occur in $A.$

Create a scalar variable $C$ that counts how many of the elements of A are between $-20$ and $20($not including $-20$ and $20).$

Solve this problem using vectorized code. Your code should not include the following MATLAB functions or keywords: if$,$ for, while. You will receive a deduction if you use any of these.
