hi, i have trouble using while loop. Where should i put the j inrement? i try fews times but infinite loop. Thanks in advance.
k = 4
j = 1
i=1
while j <= k
for n = i:40
if (G(i,11)) == j
mean = sum(G(i:10))/length(G)
i=i+1
break
end
%j=j+1
end
%j=j+1
end

What is the code meant to be doing?
Note that using length on a 2D matrix is asking for a lot of trouble. Is that length supposed to return the number of rows or the number of columns (note that it can return either depending on the actual size of G)
And naming a variable mean is also a very bad idea since it prevents you from using the mean function.
Is the switching from 2D indexing (in G(i, 11)) to linear indexing (in G(i:10)) on purpose or a major error?

This one works for me:
G = 100:1:1000;
k = 4;
j = 1;
i = 1
while j <= k
for n = i:40
if G(i,11) == j
mean = sum(G(i:10))/length(G)
i = i+1
break
end
%j=j+1
end
j=j+1
end

thanks for the explainantion, if i want to make j=2 is execute within for loop for the 2nd iteration..where should i put the j=j+1
