Hello, I don't understand. Why should I use the zeros function?
Eb=zeros(1,8640);
time1=zeros(1,8640);
diesel=zeros(1,8640);
Edump=zeros(1,8640);
Edch=zeros(1,8640);
Ech=zeros(1,8640);
In this case, I don't understand zeros(1,8640). please explain to me

"Why should I use the zeros function?"
  1. to avoid bugs by ensuring that a variable has the correct data type (often overlooked in answers).
  2. to improve efficiency by preallocating an array to the required size:

Zeros(m,n) will create a matrix of dimensions m x n with all the elements as 0. This matrix along with the ones(m,n) is often used to pre-allocate a matrix so as to save memory and time of processing.

Hope that helps!
