------------------------------------
Re-propose as describe below.
/**
* Returns the sub matrix formed by selecting certain rows and
* columns from a bigger matrix. This is a in-memory operation only.
*
* @param i0 the start index of row
* @param i1 the end index of row
* @param j0 the start index of column
* @param j1 the end index of column
* @return the sub matrix of matrix
* @throws IOException
