I often save tables to Excel for sharing with others, but if the data is too large, I need to share to a CSV file instead. Here I build a function to do that. Features covered in this code-along style video include: writetable regexprep Note, at @18:13 I think I’m looking at the... read more >>

A few weeks ago I talked about the new pause button in Release 2016a on the editor tab of the desktop. Someone asked what do you do if you want to pause your code but the editor was not open when you started it? Here are a couple of ways... read more >>

In this code-along style video I attempt to develop a script to import and analyze website page response times data, including doing some comparisons of distributions. Features covered include: readtable, with TextType='string' Table indexing hist, and subplot @media (min-width: 992px) { .containing-block { width: 100%; } } Play the video in full screen mode for... read more >>

One of the many uses of variable highlighting in the MATLAB editor is to help with moving code around. When you select variables, it shows you where they are used in the rest of the code, and therefore where it is safe for you to move those lines to. Features covered... read more >>

This morning I needed to debug an issue with a regularly used script. The code was converting numerical columns in a table to strings or categoricals by using a lookup table. I had a few levels of indirection which made it more complicated to understand what was going on. Breaking... read more >>

I’d like to be able to analyze and visualize our website but at more than 300 thousand pages and more than 20 million links, its too much information to easily digest or display. So I thought I’d explore ways to summarize it. This can let me quickly see any large... read more >>

You can’t use isempty to detect empty strings, as you would for character arrays, instead you should check for strlength being equal to zero or compare with an empty character vector. See the documentation for more information. @media (min-width: 992px) { .containing-block { width: 100%; } } Play the video in... read more >>

Each time I install a new release of MATLAB, such as 2016b recently, I turn on the editor preference “Enable data tips in edit mode”. Its not on by default. Here’s why its very useful. Follow me (@stuartmcgarrity) if you want to be notified via Twitter when I post. @media (min-width: 992px)... read more >>

I have a spreadsheet with a list of filenames in one column whose absolute location is defined relative to a file in another column. I want to be able to construct the absolute path for all of them so I can compare them with another list of absolute path filenames. To... read more >>

Its the 15th anniversary of MATLAB Central and it made me think about my contributions to the MATLAB community. My first interaction was with the MATLAB Newsgroup. I wanted see when my first post was and then when my most active years were. I could see my first post by using the newsreader... read more >>
