I have a array c of 276 elements. I want to split it into 3 separate array. The number of elements in each of these three array is within the array c itself.
vind=c(find(c>=10)) %gives me
vind =
45 45 183
I have to split the array c into three arrays with number of elements as 45, 45 and 183 respectively excluding the position of these three numbers. Pls suggest how it can be done.
with thanks

Alternatively:
loc = find(c >= 10) ;
vind = c(loc) ;
c(loc) = [] ;
out = mat2cell(c, 1, vind) ;

I accepted this answer, because its very logical, clean and simple way to split without any loop. I could do the same with loop but in a rather inefficient way than Azzi's answer. Thanks to him too.

ii=1;
for k=1:numel(vind)
jj=vind(k)
out{k}=c(ii:jj)
ii=jj+1;
end

Please add some code for the pre-allocation also. Otherwise we have to answer corresponding question next week again. Thanks.
As far as I understand, the OP wants the part from ii to jj-1 only.
