Hi all
I want to define some variablees at the beginning of the program which have the same dimensions.
for example: there are four variables as followed ani I want to define their dimensions whithout frequently repeating "zeros(Y,T)". How can i do this?
"q_counter=zeros(Y,T); tsd_sim= zeros(Y,T); r_sim=zeros(Y,T); s_sim=zeros(Y,T); "
Thanks,

zYT = zeros(Y,T);
q_counter = zYT; tsd_sim = zYT; r_sim = zYT; s_sim = zYT;
There is a technical difference between this and what you wrote, but you will only encounter that difference if you are very short on memory.
