It’s not that the Gram-Schmidt algorithm fails or is somehow invalid. The problem is that you’ve given it an invalid input: the G-S algorithm is, strictly speaking, only defined for a linearly-independent set of vectors (the columns of the input matrix). The test you’ve been told to use assumes this as well. phil-osophy modern family
