I am writing a code which requires a few zero arrays of the same dimension for a summation process in a loop, and I was wondering if it is possible to define them all at once. For example, I want 3 vectors A to C

A=zeros(5,1);
B=zeros(5,1); 
C=zeros(5,1);

How can this be replaced with one line (if possible)? Thanks.

[A, B, C] = deal(zeros(5,1));

@Kien Pham: what do you mean?:

one cell array dealt to three cell arrays.
three inputs dealt to one cell array.
three cell arrays dealt to three cell arrays.
three cell arrays dealt to one cell array.
something else?

There are lots of ways that deal can be used with cell arrays, but you have not given us any idea of what data you have, and what you are trying to achieve with it.

@Stephen Colbeldick: I was trying to deal one cell to multiple cell arrays. While trying to clarify my question to you, I was able to answer my own question by looking up deal.

Thank you anyway for your response. It really helps me think about how I write my questions to the Community next time.
