How to load multiple indexed .txt tables at once using a loop?

MOTIVATION: Hi, I want to import multiple tables such as table1.txt, table2.txt, ..., tablei.txt.

WHAT I DID: For this I wrote the following lines:

for i=1:3;
x{i}=load('table%d.txt',i)';
end

PROBLEM: I obtain the following error: ??? Error using ==> load Argument must contain a string.

QUESTION How should I write the command lines to obtain

x1=load('table1.txt');
x2=load('table2.txt');
xi=load('tablei.txt');

without needing to write each line for each i?

I thank you in advance for your help

[TAB]

for i=1:3
 x{i}=load(sprintf('table%d.txt',i));
end

Why you are using load() for reading text file ? You can do better with textscan().

Hi Tabrez,

thank you for your correction. It works well.

Now, how would I do the same using textscan()?

I wrote:

x=textscan(sprintf('table.txt'));

and obtained the message error:

??? Error using ==> textscan

Not enough input arguments.

I thank you in advance for your help

You can use textscan() based on what is content of your text file and what is your expected output.

For help type

>> doc textscan

on command window

Please give some example data of your text file and your expected output, then only i can suggest anything.
