### 3D Plots in MATLAB - GeeksforGeek

Matlab can plot vector fields using the quiver command, which basically draws a bunch of arrows. This is not completely obvious though. First we have to set up a grid of points for which to plot arrows. In other words we have to tell it for which x and y to actually draw the vector field T he surface / surf plot in MATLAB can visualize data in 3D. When I took a course in grad school on statistical image processing, I saw a very interesting plot where data is shown as a surf plot and underneath, on the ground or x-y plane, an image is shown. The pixels of the image corresponded to the points in the 3D surface and gave some extra information about the each point, sort of like an. An Arduino takes in the wind speed and temperature values at each (x, y, z) point and prints them to the serial monitor for MatLab to read.
