Cody Code-Along: R2016b Feature Challenge – String Array Basics, Part 3

Posted by Stuart McGarrity,

Here I continue with “Cody Code-Alongs” for the Release 2016b Features Challenge. This one looks at converting between strings and cell arrays of character arrays with missing values. I could not however figure out a better way how to set string elements to <missing>.
Features covered include:

string, cellstr

Making a MATLAB Function to Re-Use Code

Posted by Stuart McGarrity,

Its common when you are developing code to find that you want to re-use a piece of it for some new dataset or task. Instead of copying and pasting, always consider writing a function. Here is an example of me doing this, moving the code out and updating my script… read more >>

Features covered include:

readtable, with TextType=’string’
Table indexing
hist, and subplot

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 >>

Use strlength to Detect Zero Length Strings

Posted by Stuart McGarrity,

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.
