I tried >> x = rand(3,1) >> diag(x) array([ 0.87113114]) Isn't rand(3,1) a vector? Off list I was given the example: x=rand(3) diag(3) That works. But my x is a Nx1 matrix. I can't get it to work with matrices. Joris: The Numpy Example List looks good. I hadn't come across that before. Using Tomcat but need to do more? Need to support web services, security?
