Hello,
I´ve got a problem with the calculation of a matrix in a for loop. It seems easy to solve but I can´t find my fault in the following source code:
N=100
for i=1:10
tfail = ixN-vector
tfail_sort = sort(tfail);
t_boot=0:1:max(tfail);
z_boot=zeros(1,length(t_boot));
for k=1:length(tfail);
z_boot(k,:)=1.*(t_boot>=0 & t_boot<tfail_sort(k));
z_boot(k,:)=z_boot(k,:)+0.*(t_boot>=tfail_sort(k));
end
R_m_boot(i,:) = (1/N)*sum(z_boot); % Sum the columns
end
Can somebody help me, please?

What is the error you get?

All we see ist the failing code. But we cannot guess, what it should do.
It cannot be useful to perform
z_boot(k,:) = z_boot(k,:) + 0 .* <anything>;
The multiplication by 0 is not useful in a sum.
