Sometimes I need to display the name of a variable as a character array. This can help with the updating of variable names in code and automating the importing or exporting of multiple variables to… read more >>
This code-along video is the third in a series where I’m creating a MATLAB function to split a URL into component parts. Here I update another script to make use of this new function but it… read more >>
You may be familiar with using try/catch statements to make your code robust to errors. Matt covered them in a series of posts. A try/catch statement will catch one occurrence of an error in the… read more >>
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 >>
