1 function index = mk_multi_index(n, dims, vals) | |
2 % MK_MULTI_INDEX Compute the indices of the submatrix where dims(i)=vals(i). | |
3 % index = mk_multi_index(n, dims, vals) | |
4 % | |
5 % Example: | |
6 % index = mk_multi_index(3, [1 3], [3 2]) | |
7 % gives index = {3, ':', 2}, which will select out dim 1 = 3 and dim 3 = 2 | |
8 % So if A(:,:,1)=[1 2;3 4; 5 6]; A(:,:,2)=[7 8; 9 10; 11 12] | |
9 % then A(index{:}) = [11 12]: | |

12 index = { 1 }; | |
13 return; | |
