I would like to suggest that matrix types with structural zeros make this structure evident in the default printing. For example, the lower triangulat elements of UpperTriangular instances are guarant…

I was comparing LU- and QR-Factorization and wanted to implement parallelism. I noticed that fetching the QR-factorized matrix `fa` at the same time as the identity matrix `b` results in a segmentatio…

Basically, I cannot use `lufact` on a simple sparse matrix, but the dense version works fine.
Forgive me if I missed something obvious. Is it a result of some linear algebra concept?

Hi everyone,
while experimenting with the language and trying to port a LU factorization benchmark from the Barcelona OpenMP Tasks Suite written in C, I got **fatal error: acquirep: invalid p state**…

The following code prints different numbers depending on were the "-p N" option passed to Julia interpreter or not.
