MATLAB:Inp​utParser:A​rgumentFai​ledValidat​ion

I've attempted to develop an .exe software from .m file.

I want the software to have `logical` input; however, .exe file that is generated through `mcc -m *.m` does not accept logical input. It seems that the .exe on bash or sth read input as `char` input.

Now the error is raised as follows:

 >> ! CliSoftware verbose true
 Error using CliSoftware (line 11111) 
 The value of 'verbose' is invalid. It must satisfy the function: islogical. 
 MATLAB:InputParser:ArgumentFailedValidation

Please give me a way to allow `logical`-type input on .exe file.

I don't know about matlab specifically, but it's normal for an executable to treat all command line inputs as characters. It's normally up to you to parse the input and convert it to whatever type you want.

It's trivial to do anyway. You have plenty of options:

verbose = strcmp(theinput, 'true');  %if you only accept one case sensitive way of specifying the option
verbose = strcmpi(theinput, 'true');  %same but case insensitive
verbose = ismember(theinput, {'true', 'on', 'full'});  %if you want to allow several way of turning the option on. 
verbose = ismember(lower(theinput), {'true', 'on', 'full'});  %same but case insensitive

Dear, Guillaume

Thank you for your answer. I was obsessed with the implementation way. I'll follow your suggestion. Thanks!

Guillaume is correct. See the "Using a MATLAB File You Plan to Deploy" section on this documentation page for an explanation.
