Sometimes when you are working on a User Interface you want to use the profiler to speed up the code. However, with a UI so much time can be spent by the user rather than the code of interest that… 続きを読む >>
Recently a MATLAB user asked me how to make it possible to work with an array of structures in such a way that she could filter the array of structures and then combine the remaining fields. Once… 続きを読む >>
Sometimes MATLAB throws an error, but because the error is inside of a function you can not see what caused this error. By telling the debugger to stop execution under certain conditions or right… 続きを読む >>
In some code there is an enumerated set of choices. People will use a switch case statement to check for all but one choice and then catch that last one in the ‘otherwise’ block of their… 続きを読む >>
There are situations where you want MATLAB to remember the value of a variable from one call of a function to another call of that function. We show to use a persistent value to accomplish this. … 続きを読む >>
There are often small tweaks to functionality that you would like for a figure in MATLAB. This video shows how to add a button to a figure that will allow you to toggle the units of a y axes between… 続きを読む >>
A colleague was trying to draw some structures and do basic static analysis on them. He wanted to write a routine that would draw a pinned beam given the locations of the two pins. This can be done… 続きを読む >>
This post is a continuation of the last video where we built a simple GUI in MATLAB. This continues by showing how to run initiation code for a MATLAB GUI and explains what the handles structure… 続きを読む >>
I got a quick question today on how to make a diamond appear on an image in MATLAB. This is really an exercise in indexing and for loops in MATLAB. Let’s see how you can make an image in… 続きを読む >>
Sometimes the performance of MATLAB code can depend greatly on the algorithm or the specific functions called. In this example, we show how we use the profiler (and good knowledge of logical… 続きを読む >>
