Slice; Vector Field Plots

In today’s lesson, we’re going to be covering the following topics: 1. Slice Function 2. Vector Field Plots video coming soon Slice Function The built-in MATLAB function slice allows you to slice through the x, y, or z plane of a 3D shape. The slice can be orthogonal (perpendicular) to the specified plane, and there…

Creating Input Statements

In today’s lesson, we will be covering how to create input statements. Input statements are used in scripts to get the user to input a specific number rather than assigning one value to a variable. For example, if I wanted to make a code that added together two numbers that someone using my program would…

Overlaying Plots Versus Subplot

In today’s lesson, we will be covering the following topics: 1. Overlaying Plots 2. Subplots VIDEO COMING SOON Overlaying Plots We learned in a previous lesson how to plot simple X-Y graphs, but what if want to show multiple data sets in one plot? To do this, we can overlay plots. To do this, there…
