26 Jan 2012 Free-knot spline approximation Least squares approximation of 1D data using free-knots spline Author: Bruno Luong

Nima, it is not rotational invariant. Because the fit is carried out using the least-squares to the ordinate data (y) only.
26 Jan 2012 Truncated Gaussian Generate a pseudo-random vector X drawn from the truncated Gaussian distribution Author: Bruno Luong

Raymond, there exist no random variable in [2 500] with mean = 0. The mean must be in [2, 5000] regardless the distribution. Thus what you ask is mathematically impossible.

Andrea, go to the folder where all the files reside before invoking the installation command.

@jianbo,

Try to change

memset((void*)(data+p0), 0, sizeof(double)*nz)

and

/* in case the positive set is unordered */

Katherine, you need the optimization toolbox, especially linprog()

Dear Bruno,

How do a generate from the normal distribution with mean zero and standard deviation 1 a truncated normal on the range [2 500]? I calculate the this random variable has a standard deviation of 0.3381. When I try [X meaneff sigmaeff] = TruncatedGaussian(0.3381, [2 500], 1) I get an error message.

Hey Bruno thanks for the awesome package, it works great!
I just have one problem, is this approximation rotation invariant? Since when I intentionally rotate my data points the knots are completely different with increased fit error compared to the baseline profile! please let me know if I am doing sth wrong
