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.

A3-mm-thick panel of aluminum alloy (k 177 w/m-k, c 875 j/kg-k and ? = 2770 kg/m) is finished on both sides with an epoxy coating that must be cured at or above t,-150°c for at least 5 min. the production line for the curing operation involves two steps: (1) heating in a large oven with air at ts,0-175°c and a convection coefficient of h, 40 w/m2. k, and (2) cooling in a large chamber with air at 25°c and a con- vection coefficient of he 10 w/m2.k. the heating portion of the process is conducted over a time interval te which exceeds the ime required to reach 150°c by 5 min (h = r + 300 s). the coating has an emissivity of ? = 0.8, and the temperatures of the oven and chamber walls are 175 and 25°c, respectively. if the panel is placed in the oven at an initial temperature of 25°c and removed from the chamber at a safe-to-touch tempera ture of 37°c, what is the total elapsed time for the two-step curing operation?
