how to rename or move files

Hello,

I want to rename or move files from one name to another in the same folder. i write following script. but it gives errors.

clear all;
close all;

year=1998;
mn=1;

for dd=1:9
display(['dt_ref_med_merged_madt_h_',num2str(year),'0',num2str(mn),'0',num2str(dd),'.nc']);
movefile (['dt_ref_med_merged_madt_h_',num2str(year),'0',num2str(mn),'0',num2str(dd),'.nc' 'dt_ref_med_merged_madt_h_',num2str(year),'_',num2str(dd),'.nc']);

end

>>mytest
dt_ref_med_merged_madt_h_19980101.nc
??? Error using ==> movefile
Can not copy or move a file or directory onto itself.

Error in ==> mytest at 10
movefile (['dt_ref_med_merged_madt_h_',num2str(year),'0',num2str(mn),'0',num2str(dd),'.nc' 'dt_ref_med_merged_madt_h_',num2str(year),'_',num2str(dd),'.nc']);

how can I fix it ?

thanks.

See the functions sprintf and datestr

"from one name to another in the same folder." &nbsp I cannot see that you provide "another name"

movefile (['dt_ref_med_merged_madt_h_',num2str(year),'0',num2str(mn),'0',num2str(dd),'.nc']... 
, ['dt_ref_med_merged_madt_h_',num2str(year),'_',num2str(dd),'.nc']);

"|],[|" in the middle (to split the unreadable code into two names) was missing.

EDIT: I find this easier to read

    y = 2014;
    m = 1;
    d = 23;
    sprintf( 'dt_ref_med_merged_madt_h_%s.nc'   ... 
            , datestr([y,m,d,0,0,0],'yyyymmdd') )

    ans =
    dt_ref_med_merged_madt_h_20140123.nc
