[Numpy-discussion] Question on LinAlg Inverse Algorithm

Hello All,

Last week I posted a question involving the identification of linear dependent columns of a matrix... but now I am finding an interesting result based on the linalg.inv() function... sometime I am able to invert a matrix that has linear dependent columns and other times I get the LinAlgError()... this suggests that there is some kind of random component to the INV method.  Is this normal?  Thanks much ahead of time,

MJ
