This code-along video is the second in a series where I’m creating a MATLAB function to split a URL into component parts. Here I add more tests, return more components, and add a parameter to… read more >>
I often need to break up a URL string into components such as protocol, hostname, file path, query parameters, etc. Here, I create a function to do this, similar to the fileparts function in… read more >>
On an existing post, a MATLAB user asked how to vertically concatenate a number of matrices taken from MAT-files. Here is a code-along of me working through a couple of options for this.

I often need to compare long lists of strings, usually URLs. If I have less than a few thousand, and the data is already in Excel, I will use the MATCH and INDEX functions in Excel to do this…. read more >>
When your MATLAB code encounters an error and you have “dbstop if error” enabled, the file in which the error occurs is opened in the editor (together with its calling files). When the… read more >>
Sometimes when I record a variable with the saveValue function, it is a mistake, or it was a test, or it was some outlier that I do not want to keep forever. In this case, the simple method of… read more >>
It can be frustrating when a script that has been running for a long time, perhaps for many hours, fails just before it finishes. This video shows a couple of techniques to address this issue: saving… read more >>
I often need to export data from MATLAB to Excel. As the files are used by others, I like to format them nicely for easy viewing and browsing. To do this, I simply create a spreadsheet with all the… read more >>
In Release 2016a, you can now pause a running MATLAB program and enter debug mode. Here, I use this feature to stop a long running script to confirm it is working correctly.
