I have an array of strings:

listboxItems = cellstr( get(handles.listbox_dat, 'string') );

The array is a list of .dat files. "something.dat,etc.dat..."

I want to import a certain .dat file which for the purpose of this question is the value "a" in the array.

When I type the following it says "unable to open file"

importer = importdata(listboxItems(a));

The file is in the Matlab folder and I am able to import it via the main matlab command window. I also check with the aid of a "static text" to show listboxItems(a) with the following:

set(handles.text1,'string',listboxItems(a))

which shows "something.dat" and yet the next line that asks for that data to be imported it is unable to open the file. Because of the error I know that the string is "something.dat" and not just "something"

Anyways any help is greatly appreciated.

Thanks, Shane

Thank you soo much. I went to visit a friend to ask him to help, and he told me that the element from the listbox was delivering a cell and not the string itself and that either:

importer = importdata(listboxItems{a});

or

importer = importdata( char(listboxItems(a)) );

would work, but because as I log on now and see this correct answer you answer was accepted. <3

Thank you for your help.
