Some errors happen in MATLAB infrequently. If you don’t know the conditions when they occur, setting a breakpoint might not work. Using DBSTOP if error will have MATLAB stop on a line in the… read more >>

Simple example of storing data as a matrix or structure

When we design a program, the way we store our data will have an effect on how our code looks as we manipulate that data later. In this video we had the choice to store the coordinates of a robot… read more >>

Vectorizing code in MATLAB

When you vectorize code, you avoid looping through an array and instead do operations on the matrix level. This avoids for loops in MATLAB. The reason for vectorizing are often stylistic…. read more >>

Adding callbacks to lines and axes in MATLAB 8

A callback is a function that gets called when you perform certain actions. For instance, you might want something to happen when you click on a line in MATLAB, or when you move the mouse in MATLAB…. read more >>
