I would like to publish a Matlab code, which needs some input from the user (a single string). The code runs fine, but when I am trying to publish it I get
Error using input
Cannot call INPUT from EVALC.
Error in test (line 185)
userinput = input('Enter the code here\n', 's');
Is there any workaround?
If you click the little drop-down menu next to the publish button, you'll see an item called Edit Publish Configurations. If you select that (while the file you want to publish is open in the editor), you'll see you have a MATLAB expression that you can edit. This is the MATLAB code that gets executed when you publish the script, and by default it's just the name of your script.
Let's say your script is called myscript, so by default the published expression is just
myscript
You can edit the expression to be:
userinput = 'example';
myscript
Then this will be run when you hit the publish button.
Within your script, change the line
userinput = input('Enter the code here\n', 's');
to
if ~exist('userinput', 'var')
userinput = input('Enter the code here\n', 's');
end
Now your script will run as normal (assuming you don't have a variable 'userinput' in the workspace), and your script will publish successfully.
Hope that helps!
input command from your script, and creating a second script that calls input followed by the publish command on your original script? Then run that.If you want to publish your matlab file (xyz.m) without executing the code , then use the following.
% To stop executing the script before publish
opts.evalCode = false
% Similarly here are some more options
% If you want to publish only comments and not code, then
opts.showCode = false
% Publish doc format, html by default
opts.format = 'html'
% Catch error before publishing
opts.catchError = true
% Publish doc output path
%opts.outputDir = <path>
% Finally publish
publish('xyz.m',opts)
Instead of using the input command use inputdlg instead. So you would have;
userinput = inputdlg('Enter the code here:');
This creates a dialog box generating the inputted values as a string and allows you to execute and publish the code
There is no direct way of using input() in a code you want to execute & publish the results. Workarounds are possible. I would simply split the code into two (or more) parts. First part will use input() and then publish(). The other part(s) will be the actual code while the first part forms a wrapper on second. The publish() in first part would call the second (and/or other) part(s). This gives flexibility to control what's to be shown in the generated output to properly indicate that input() is being used.
publish(mfilename). Only scripts may be published.
