--------------------------------
Summary: invalid argument ranges in matrix_extract
Key: MADLIB-1006
URL: https://issues.apache.org/jira/browse/MADLIB-1006
Project: Apache MADlib
Issue Type: Bug
Components: Module: Linear-Algebra Functions
Reporter: Yui Noma
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.
