The new release of MATLAB R2014b brings a new graphics engine. This allows for some new capabilities such as rotating tick labels and using dot notation in referencing graphics properties. These… 続きを読む >>
When you have timers and callbacks in your code, it can be difficult to find out when certain errors are occuring. Use DBstack to find the debug stack trace in MATLAB. This will allow you to find… 続きを読む >>
In last week’s post, I showed how to generate code in MATLAB to automatically read in a file. In this video I show how to make a simple wrapper function around code generated in that way. … 続きを読む >>
I recently was asked how to import from Excel but only bring in a certain part of the file. You might want to do this if you have headers or just want a small part of the spreadsheet to come into… 続きを読む >>
This video is a follow on to last week’s. Instead of making a line with different colored markers in MATLAB, we will be making a multi-color line in MATLAB. This is actually stretchig the… 続きを読む >>
MATLAB Answers is a great resource for getting help from the MATLAB community. There was a recent question that inspired this video. I took the question to mean, how can I change the color of a… 続きを読む >>
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… 続きを読む >>
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… 続きを読む >>
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…. 続きを読む >>
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…. 続きを読む >>
