Hi,
Anyone please can send/point me example program that uses gsl_bspline_knots function? The one GNU has given in user guide uses gsl_bspline_knots_uniform function. I am new to GSL and doing some research work using it. I've stuck over this problem for last few days and I tried few things but it didn't work. What I want to do is quite simple: I've intermittent X values which are not in any sequence (e.g. 6, 16, 28, 33, 46, 67, 76, 79, 86.. etc) and I've corresponding Y values (1280, 1302, 1325, 1295, 1187, 1123, 1024, 987, 865.. etc) All I want to do is computes a linear least squares fit to this data using cubic B-spline basis functions, so that I shall get output the smoothed curve of Y values. Also, for sequential X values (for e.g. values between 6 to 16 OR 16 to 28 in above example) I shall get corresponding Y values on the smoothed graph obtained by B-spline functions. I believe I need non-uniform knots to do this (I might be wrong. Please correct me if I am) Tell me if I can achieve this using uniform knots. In either case, example code would be greatly appreciated. Many thanks in anticipation, Atul D.
