how to split large vector in small vector groups ?

Hello

how to split large coloumn vector in small vector group ?

i am using audio file input, it gave me very large coloumn vector and because of this simulation takes more time.

this is code where i am using audio file as an input.

********************************************************

[fi fs]= wavread('sound1'); % /* read file into memory(its 44.1 khz signal) */

fi2 = fi(:,1); % taking left column vector as a mono input

tt=0:1/fs:(length(fi2)-1)/fs; % /* time duration */

ti=tt;

[T,Y]=ode45(@(t,y) myeqd(t,y,ti,fi2),tt,[1;1;30]);

plot (T,Y)

********************************************************************* thank you

Use reshape function
