One of my continuously running MATLAB scripts just failed and has stopped at a breakpoint (I had set dbstop if error). So I need to debug it to understand why and fix it.
Features covered in this code-along style video include:

string arrays and processing with split, ismember, extractBefore
arrayfun
Debugging in general

I often export to Excel to share results with others. In doing so I control the format of the output with a template with column widths and heading colors that I have talked about in previous videos (saving to a template, replicating a worksheet template). However, if I change the… read more >>

I have a table of logical data, with only one true in a row. I want to find the variable name (column header) for each row where the value is true.

I have a folder full of video files (MP4s) which I want to move based on their content. Specifically, if the file has no blank sections at the beginning or end I want to move it to another folder. So I need to read some frames from file and moved… read more >>

Here I step through how I implemented communication between two MATLAB instances on two different machines. One MATLAB (the server) stores a 40GB data set that I want another MATLAB web app (the client) to access. This avoids the web app having to re-load this large data set each time…. read more >>

If you remember, my app creates a timer to control the execution of the main loop. It doesn’t however delete the timer. As a result, when you close the app, the timer is left behind which is untidy. Here I use the UIFigureCloseRequest callback to stop and delete the timer… read more >>

Sometimes the text files I need to read have an irregular format, i.e. it changes row-to-row. MATLAB file reading functions that expect columns of data (e.g readtable), need a uniform format to work. So if this is not the case, you need to read the file line-by-line, then split the… read more >>

Now that I’ve got most of my data processing and plotting working, I think I can start using App Designer to put it all together. I’m going to move most of the code that I have developed into the app. I will need to make modifications to the signatures of… read more >>

So far I have some charts displaying my server traffic in a while loop. Next, I think I want to execute the chart updates at a regular rate, so I’m going to move the contents of the loop into a separate function and call it from a timer object. This… read more >>

In my last post, I worked on accessing a set of continually updating log files from a server. Here I will review what I did to tidy up my code, then work on plotting the streaming data as it comes in.
