how to use a for cycle with strings as variables

Hello,

I would like to write 10 variables at once in separate files. Is there a way to make my code more efficient? I am thinking of using a "for" cycle, but I can't do it in this case.

writematrix(data1, "data1.txt");
writematrix(data2, "data2.txt");
writematrix(data3, "data3.txt");
writematrix(data4, "data4.txt");
writematrix(data5, "data5.txt");
writematrix(data6, "data6.txt");
writematrix(data7, "data7.txt");
writematrix(data8, "data8.txt");
writematrix(data9, "data9.txt");
writematrix(data10, "data10.txt");

I thank you in advance,

Best regards,

Avoid numbered variable names.

Use indexing in a loop.

As soon as you do not hide indices in the names of variables, but use arrays instead, the code is trivial:

for k = 1:10
  writematrix(data{k}, sprintf('data%i.txt', k));
end

By the way, prefer to include leading zweos for the numbering of the files:

sprintf('data%03i.txt', k)

Then the alphabetical order is the numerical order also.
