load ascii data with multiple name

dear all,

I have some data with name ZA000060.TXT, ZA000120.TXT, ZA000180.TXT ..... at the same time I load data with :

for k=60:60:300
    aa = sprintf('%d',k);
    load (['ZA0000' aa '.TXT'],'AAA')
end

but there is error when load second data because the zero number.

unable to read file "ZA0000120.TXT"

Any help would be great,

Best regard,

[Stephen23]

@gugum gumbira : Why do you think that " error when load second data because the zero number" ?

You don't give us the complete error message, and there is no reason why a zero digit in a filename would cause any error. Please show us the complete error message.

Also note that it would be much better to load the data into one cell array:

V = 60:60:300;
C = cell(size(V));
for k = 1:numel(V)
    filename = sprintf('ZA000%03d.TXT', V(k));
    C{k} = load(filename);
end

Do NOT load the variables individually, this will make your code much more complicated.

Edit: simplify example code.

Thanks for quick reply :) with this syntax for k=60:60:300 aa = sprintf('%d',k); load (['ZA0000' aa '.TXT'],'AAA') end

I got this error

Error using load Unable to read file ZA0000120.TXT: Tidak ada berkas atau direktori seperti itu. the right load is "ZA000120.TXT" not "ZA0000120.TXT"

and using your syntax I got this error

"Assignment between unlike types is not allowed." thanks for your help before :)

@gugum gumbira: I corrected and tested my example.

[gugum gumbira]

I got some errors with your syntax. would you please give full explanation about load the data into one variable

thanks

You didn't replace the ellipses with the filename. Specify the filename and it will work.

for k=60:60:300
    filename = sprintf('ZA000%03d.TXT', k);
    ZA{K} = load(filename);
end

I got nothing with this script :( I hope the data would be load for each .TXT data

Thanks

To elaborate on Walter's answer. We suspect the problem is that you need a variable number of 0s before the actual number, depending on the actual number of digits.

This is what the '%03d' does in the formatstring of sprintf. It says prints the number as decimal (the d) with at least 3 digits (the 3) padded by zeros if necessary (the 0).
