Problem with ?orgqr for full Q

Hey Guys,

This is a 'Complete the reference manual' thread.

There is a very important information missing in ?orgqr reference manual.
If we are interested in computing all 'm' columns of Q using
?orgqr(m, m, p, a, lda, tau, work, lwork, info)
the second dimension of array 'a' -->MUST<-- be at least 'm', so it can store a 'm' by 'm' matrix. Otherwise the result will be wrong and there will be some serious memory leaks.
Please add this information to your reference manual, both html and pdf.

Cheers

Dear Fernando,
Let me quotethe manual for ?orgqr:

"The second dimension ofamust be at least max(1,n)"

And n = m in the case.

So, information is already in reference manual.
