Easier way to rename files?

Hi all,

I run a code where in the end I rename a bunch of output files based on the date that the data was procured. So if my code finds xData, yData, zData and tData and I want to rename it as the following

xData060912=xData;
yData060912=yData;
zData060912=zData;
tData060912=tData;
clear xData yData zData tData

Is there an easier way to do this? rather than renaming the arrays manually everytime. Can I just input 060912 in one line and use a function that does it automatically?

Thanks, NS

See "How can I create variables A1, A2,...,A10 in a loop?" in the Matlab FAQ.

Something like this is often recommended

    str_name = sprintf( 'xData%06u', num )';
    Data.(str_name) = xData;
    etc.

Thanks. But doesnt "Data.(str_name) = xData;" form a data structure. I dont want that. I want each array to be named individually.

NS: That approach is not recommended as it usually leads to problems. The approaches in the FAQ that Per referenced are more appropriate.

@NS Did you read the entry in the FAQ?
