What I have been asking during past days was about making and solving linear equation (y = ax) from a data text file. With your help I achieved to make one equation from the data but there are 49 other equation left which I am gonna make it somehow automatic. What I read from the data is a matrix (say, 200 x 50) in which the first column is the observation vector (y) and others are columns corresponding to design matrix (a), which I struggled to make that finally. So I am gonna make that automatic for other equations (columns), but I don't have any clue how to do that with loop and without loop. Could you give some kinda strategy and shed lights on that? -- View this message in context: http://old.nabble.com/make-equations-without-loop-tp34407576s24193p34407576.html Sent from the J Programming mailing list archive at Nabble.com.
