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.

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.

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 >>

Today I’m just making a small modification to an existing script to store a variable with the saveValue function I developed a while ago. The variable is of type duration, part of the recently added set of datetime functions.
Features used in this code-along style video include:

datetime and duration
tables
