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

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.
