vlt.data.ind2subD

  IND2SUBD - retrieve the sub-indexes for only a particular dimension

  SUB_INDIXES = IND2SUBD(MATRIX_SIZE, X, N)

  Given a linear index X in a multi-dimensional matrix with dimensions specified by 
  MATRIX_SIZE, this function returns the corresponding sub-index in dimension N.

  Inputs:
    MATRIX_SIZE: A vector specifying the size of each dimension of the matrix.
    X: The linear index.
    N: The dimension for which to return the sub-index.

  Output:
    SUB_INDEXES: The sub-index in dimension N, in uint64 format.
