Introduction to Chemical Engineering Computation with MATLAB - Example 6.6 from Chapter 6: Functions of vectors

Screen cast of Professor Paluch working through Example 6.6 from "Introduction to Chemical Engineering Compuation with MATLAB." In this example we will create a logical function to check if all of the elements of the input vector are positive. A copy of the M-file from the screen cast is provided below. https://drive.google.com/file/d/1xViVL1ThBt7tn1cyQivH1VFN6e-zZpZS/view?usp=sharing
