Dynamic Variable Name

[AK1984]

Hi Guys,


I need to make this expression changes dynamically:

VariableX = importdata ('FilenameX.out');

where, everything is constant but the "X" is a integer number that changes from 1 to 5

for example: hello4 = impotdata ('file4.out');



Please Help Meeeeeeeeeee...

Thanks

Is there something lacking in Matlab's help files on string functions and operations?

Use an array. Something like:

var(x) = importdata(['filename' int2str(x) '.out'])

Hope that heeeeeeeeeeelps.

One of the most commonly asked questions when those new to Matlab try to read multiple files.

You can use the "eval" function to construct variable variable names, but that gets you into a deep hole of confusion and terrible code.

Use cell arrays instead. Plenty of help and examples in the Matlab docs exist.

It sounds as though you're trying to read a large number of files into MATLAB... maybe using the DIR command to build your list would be the way to go?

files = dir('Filename*.out');
for n=1:length(files)
    data{n}=importdata(files(n).name)
end
