Hello,
I'm new here and in matlab, so if I do mistakes, please, tell me.
I'm working on my thesis and I need to extract some matrices and elements, but I can't write the for-loop exactly. For example, I have to read six matrices (but then I'll have more matrices) and this is too long
matrix_1 = dlmread('/scratch/matrix_1');
matrix_2 = dlmread('/scratch/matrix_2');
matrix_3 = dlmread('/scratch/matrix_3');
...
...
and so on. I'd like to do a for loop, to read the matrices, but I don't know how. I tried with something like
number = [1, 2, 3, 4, 5, 6];
for ii = 1 : 6
tmp = dlmread(sprintf('/scratch/matrix_$i', number[ii]));
eval(sprintf('Matrix_final_$i = tmp', ii));
end
but it doesn't work :( In the same way, after, I have to extract the second column of each matrix, because is too long to do
n1 = matrix_1(:,2);
n2 = matrix_2(:,2);
...
...
I don't understand how to use the index ii in the for loop like a string in the name of the matrices. Does somebody know if it's possible?
Sorry for my English,
thank you!
