Just installed Matlab 2023 on a dual-screen laptop. Can't launch documentation. Similar issues for all the options under RESOURCES tab.

Error using strsplit
First input must be either a character vector or a string
scalar.

Ran in:
Let's make sure you don't have a function named split that's taking precedence over the split function included in MATLAB. What does this command show?
which -all split
/MATLAB/toolbox/matlab/strfun/split.m split is a built-in method % string method split is a Java method % java.lang.String method /MATLAB/toolbox/matlab/bigdata/@tall/split.m % tall method /MATLAB/toolbox/matlab/datatypes/calendarDuration/@calendarDuration/split.m % calendarDuration method /MATLAB/toolbox/wavelet/wavelet/@dtree/split.m % dtree method /MATLAB/toolbox/wavelet/wavelet/@wdectree/split.m % wdectree method /MATLAB/toolbox/wavelet/wavelet/@wptree/split.m % wptree method
If it shows something that's not under the matlabroot directory try renaming that file or removing the directory containing it from the MATLAB path.

Here's what I have. Nothing suspicious.
C:\Program Files\MATLAB\R2023a\toolbox\matlab\strfun\split.m
split is a built-in method % string method
split is a Java method % java.lang.String method
C:\Program Files\MATLAB\R2023a\toolbox\matlab\bigdata\@tall\split.m % tall method
C:\Program Files\MATLAB\R2023a\toolbox\matlab\datatypes\calendarDuration\@calendarDuration\split.m % calendarDuration method

Can you set an error breakpoint and show us the output of whos when MATLAB stops at that breakpoint?
While we're at it, I don't think it's quite as frequently overloaded as split but could you show the output of which on string as well?

Hi Steven,
Thank you so much for your help! I discovered that there was a toolbox on my path with a strsplit that didn't accept " ".
