Undefined function 'replace' for input arguments of type 'char'.

Hi, I try to make my program work, but I am struggeling a bit with this mistake. I want to cut off the ending of my file name, e.g. 'NACA_65-209.txt'. Unfortunately the following code is not answering anything. When I try to use e.g. 'strrep' instead my following program ends with errors.

Thank you!

 function AirfoilName = get.AirfoilName(ObjectName)
            %Replace the file extension by nothing, to receive the
            %AirfoilName.
            oldString = '.txt';
            newString = strcat('');
            AirfoilName = replace(ObjectName.FileName, oldString, newString);
        end

Which release of MATLAB are you using? I suspect you're using a release prior to release R2016b, which is when the documentation indicates the replace function was introduced.
