I have a GUI that imports a .mat file full of data, and i have a function that i enter at the moment to call the file into the GUI from a command window - it is simply Add(Volts) where volts is the file name. Is there any way of getting round having the brackets or using a different call command? It has to use the file name (with my current configuration) as it then calls on matrices within Volts (eg Volts.Light etc).

Thanks

If you are calling with a literal string, such as

Add('Volts')

then you can take advantage of Command/Function duality and code this as

Add Volts

with no ()

This cannot be (easily) used if Volts is instead a variable that contains a string, such as

Volts = uigetfile('Which Volts file?');
Add(Volts)

Should have clarified, it is a variable that contains a string!

It is not impossible but it is not good programming. You would have to have the Add routine evalin('caller') the string it received, in order to get the name of the file that it was to load.
