COO's index list are represented as a NxM matrix, where N is the number of non-zero values, and M is the number of dimensions of a sparse tensor. indicesBuffer stores the location and size of this index matrix. The type of index value is long, so the stride for the index matrix is unnecessary.
For example, let X be a 2x3x4x5 tensor, and it has the following 6 non-zero values:
X[0, 1, 2, 0] := 1 X[1, 1, 2, 3] := 2 X[0, 2, 1, 0] := 3 X[0, 1, 3, 0] := 4 X[0, 1, 2, 1] := 5 X[1, 2, 0, 4] := 6
In COO format, the index matrix of X is the following 4x6 matrix:
[[0, 0, 0, 0, 1, 1], [1, 1, 1, 2, 1, 2], [2, 2, 3, 1, 2, 0], [0, 1, 0, 0, 3, 4]]
Note that the indices are sorted in lexicographical order.
