Hello All,
I created a coding rules option object and saved it into a .mat file. Whenever i have to perform polyspace verification i just load .mat file ans assign it to option object using following command.
prj.Configuration.CodingRulesCodeMetrics.MisraC3Subset = misraRules;
here 'prj' is polyspace project object and 'misraRules' is coding rules option object.
I am getting following object while loading .mat file.
SWITCH expression must be a scalar or a character vector.
Error in polyspace.option.Item/checkValue
Error in polyspace.option.Item/set.Value
Please guide.

I have never worked with Polyspace, but I don't see where you are actually loading data from a mat file into a variable. Where are you doing that?

You have to share the commands you are using for us to see what might be happening.
If you are simply doing something like this, this seems to work.
>> misraRules = polyspace.CodingRulesOptions('misraC2012'); % Creating rules object
>> misraRules.Section_2_Unused_code.rule_2_1 = false; % Some rule disabling
>> save('file.mat','misraRules') % Saving to mat file
>> clear % Starting from a clean workspace
>> load('file.mat','misraRules') % Loading rules object from mat file
>> proj = polyspace.Project; % Creating project object
>> proj.Configuration.CodingRulesCodeMetrics.MisraC3Subset = misraRules; % Assigning rules to project

One question: are you generating and loading the mat file using the same release of MATLAB/Polyspace ? Or is it possible that the mat file was generated using a different version? Actually, if you can give the version numbers of your MATLAB and Polyspace, it will help.

I think that could be the issue as .mat file is created with MATLAB\polyspace 2020b and i am using it on MATLAB\Polyspace 2018b
