If you are searching for a user-friendly and very robust tool for SERIOUS matrix analysis, look no further. This beats Wolfram's Linear Algebra, Matrix Studio, Math Studio, etc. hands down. It has functionalities that no other similar app has, including all four subspaces and projections onto subspaces, orthogonality, and on and on. I am dumping my other paid apps for matrix analysis because this IS the very best. A personal and heartfelt thanks to the developers. Kudos indeed.

Does basically everything!! from Gauss elimination to QR Decomposition, even finding matrix nullspace. Can't say anything much, but 'perfect' perhaps could be the right word. *I hope the devs could do something with the name & descriptions, currently when people are searching 'Linear Algebra' this app isn't exactly easy to be spotted*
