Is the same
C:\Users>List = dir(fullfile(matlabroot, '**', 'helperGaitPlot.*')) List Folder
'List' is not recognized as an internal or external command,
operable program or batch file.
C:\Users>List.folder
'List.folder' is not recognized as an internal or external command,
operable program or batch file.
C:\Users>List = dir(fullfile(matlabroot, '**', 'helperGaitPlot.*'))
'List' is not recognized as an internal or external command,
operable program or batch file.

You have to run the shown commands inside Matlab, of course, not in the shell of your operating system. Start Matlab and run the commands in Matlab's command window.

Try this:
query = which('HelperGaitPlot.m')
When I run it, I get:
query =
'C:\Users\<MyUserNameOnThisComputer>\Documents\MATLAB\Examples\signal\GaitAnalysisExample\helperGaitPlot.m'
I am also running R2018b.

I guess you are using matlab version 2018b.

If I remember correctly, it just loads and displays the file. It doesn’t do any processing, so you’re not missing anything by not having it.

It still not working even with Matlab version 2018b.
It said:
Undefined function 'helperGaitPlot' for input arguments of type 'char'.

This means, that you have installed the Signal Processing Toolbox, but either no license for it or removed it from Matlab's path.

Let me guess: You typed
helperGaitPlot('als1m')
in the command shell of the operating system? Then the problem is clear: Run it inside Matlab. Start Matlab and type the commands in Matlab's command window.

I typed in Matlab's command window, here is it:

The first code for the link is:
helperGaitPlot('als1m');
xlim([0 30])
