Why should I use the zeros function?

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:

It is for performance reasons:

Answer 2

[Durganshu]

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!
