Hamid - are HighWind, HeavyIce, BrokenWire local variables in your code? Are they arrays, scalars, or something else? In the Command Window, just after running the above code, type

whos

to display all local variables, their sizes, etc.

I would use the inputdlg function instead. It’s easier, and doesn’t clutter the Command Window:

LoadCase=inputdlg('Please specify the loading condition number (HighWind/HeavyIce/BrokenWire) ! ');
LoadCase = str2num(LoadCase{:})

This asks for and then displays your ‘LoadCase’ variable. Remember that ‘LoadCase’ is a cell, so if the response is supposed to be a number, you need to convert it to a double as I did here with the str2num function.

If the response is expected to be a string and not a number, use this to convert it to a string:

LoadCase = char(LoadCase)

Cell arrays are extremely useful, but in most instances it is necessary to convert them into another variable type to use their elements.
