Code has already been provided to define a function named vectorFun that accepts a single input variable A that is a column vector of 100 random numbers with values between -50 and 50. Add commands to do the following operations and assign the results to the indicated output variable names: 1. Generate a second column vector B that consists of only the negative numbers in A in the same order in which they occur in A. 2. Generate a third column vector C that consists of only the positive numbers in A but this time sorted in order from smallest to largest 3. Generate a fourth scalar output D that counts how many of the elements of A are between -20 and 20. Your code should NOT include the following MATLAB functions or keywords: if, for, while. Note the variable A is defined as a function input. Do not overwrite the value in your code.
