How to fix error in matlab code for the assignment of path?

I am using following lines of matlab code;
baseSNAP = "C:\Program Files\esa-snap\bin\gpt.exe";
cmd = [baseSNAP, aoFlag, out, oType, granule];
system(cmd);
it is giving the following error
Unrecognized function or variable 'baseSNAP'.
I request to please suggest me how to fix this error.

Presuming the other variables are defined, that code snippet would appear to be ok, but out of context by itself we can't tell what might have caused the error.

Post sufficient to reproduce the error here; creating that may well let you find and fix the problem yourself.

Thank you very much for your kind suggestions.

If it happened that there was a function named baseSNAP, and you have a call to that function, and as well you later assign to a variable named baseSNAP -- then the call to the function would generate that error message instead of calling the function or using the variable.

For example,

test()

Unrecognized function or variable 'abc'.

Error in solution>test (line 4)
abc()

function test
abc()
abc = 5;
abc()

end

function abc
    fprintf('here\n');
end
