MATLAB error for input arguments of type char

Asked by Robert
on 22 Apr 2013
??? Undefined function or method 'LoadDataFile' for input arguments of type 'char'.

this keeps appearing every time I am running the code:

FileName=[GroupNamePartOfFileName FlywheelPartOfFileName int2str(InertiaVariant) PressurePartOfFileName int2str(pCase)];
        DualYes=0;  % data file is in dual format including errors in adjacent columns
        [t,RPM]=LoadDataFile(SourceDirectory,FileName,FileExtension,DualYes);

any help as to why this is happening?

It occurs because you do not have a routine named LoadDataFile . MATLAB does not have a routine by that name.

My Lab teacher wrote this program for us... what should I use instead of this?

Your lab teacher might have supplied a routine by that name. Or might be expecting you to write the routine.

I think I understand. This could be possibly be a separate m file right?
