-------------------------------1144685284 Content-Type: text/plain; charset="US-ASCII" Content-Transfer-Encoding: 7bit Dear all, I am searching for some code that can decompose rectangular matrices according to SVD. Unfortunately, rb-gsl can only handle square matrices. Also, I've have some strange installation error with the linalg library. (I've posted a message to the list about this). Is there any other software that can singular-decompose a matrix that is rectangular and maybe really big and "very rectangular" ? Can someone who uses linalg tell me what options to use to tell install.rb what options to use ? Thank you very much! Best regards, Axel -------------------------------1144685284--
