oh...check again i fix that...

What's the overall objective?
And what do you want to do with the nested for loops?
for k=1:20
for iii=1:404
a(k,iii)=sig(k,iii+1)/sig(k,iii);
sig(k,iii)=sig(k,iii)*a(k,iii);
end
a(k,405)=1.3;
SS(k,405)=sig(405)*a(405);
end
"im trying to calculate 'a' and 'sig' so i have new values for next time"
You wrote this in a comment below. Could you elaborate on this?

On the second pass through the for k = 1:20 loop, you are trying to access the second row of sig, but it only has one row.

what should i do? im trying to calculate 'a' and 'sig' so i have new values for next time... at last i should have 20 row and 404 column value

The indexing problem is that ‘sig’ is preallocated as a vector:
sig = zeros(1,405); % Preallocate the array
Preallocating it as a matrix solves that problem:
sig = zeros(20,405); % Preallocate the array
% clc
% clear all

In line 6, 405 sigmas are produced. Now, for example, sigma 2 is divided by sigma 1 to obtain a coefficient or ratio and is multiplied by sigmas to produce a new sigma... This process continues until 20 rows of sigma are produced.

I changed the original vector ‘sig’ to ‘sigv’ to avoid confusion.
It seems that was all the first loop was doing anyway, so that step can be vectorised.
In the ‘SS’ assignment, ‘sig(405)’ is always going to be 0 because it is preallocated as 0 until it is overwritten at the very end. It turns out to be all 0 except for the last column, since that was the only column that was assigned anything other than 0.
