MATLAB: Pre allocating triple loops

preallocating

hi,
how to pre-allocate this:
for ii = 1:numel(L);
for jj=1:numel(L);
for kk=1:45;
c=cross(L1(ii,:),a{jj}(kk,:));
end
end
end

Best Answer

n = numel(L);
c = cell(n,n,45);
for ii = 1:n
for jj = 1:n
for kk = 1:45
c{ii,jj,kk} = cross(L1(ii,:),a{jj}(kk,:));
end
end
end
