Description

To whom it may concern,

Hello, I'm a newbie to use MADlib in PostgreSQL 9.4. When I was reading the document, I may find a bug related to the functions, matrix_extract_row, and matrix_extract_col. The two function extract a row/col specified by the argument. But it does not work well for the last row/col. This is caused by the inconsistency related to the indices because the index of a MADlib matrix must start from 1 but the index of the function matrix_extract defined in ports/postgres/modules/linalg/matrix_ops.py_in starts from 0.
