This submission contains an interface to a LBFGS solver for unconstrainted minimization problems of the formmin_{x} f(x) + c*|tilde{x}|,where x are the parameters, f is a scalar valued real function, c is a positive scalar (default value=0), |.| denotes the 1-norm, and tilde{x} is some subset of...

Find the projection of point P in R^n on the ellipsoidE = { x = x0 + U*(z.*radii) : |z| = 1 }, where U is orthogonal matrix of the orientation of E, radii are the axis lengths, and x0 is the center.Or on generalized conic E = { x : x'*A*x + b'*x + c = 0 }.The projection is the minimization...

Program FFT2SURF plots double Fourier series representations for several different surfaces. The figures show effects of the number of series terms and use of Lanczos sigma factors to smooth Gibbs oscillations. The Fourier series of a doubly periodic function with periods px and py has the...

If you like the idea behind MATLAB's linsolve or Tim Davis' linfactor, you might find trilin useful as well.Let's say you have a generalized least squares problem, x = C * u C = inv(N)where N = inv(A' * inv(V) * A) u = A' * inv(V) * bMatrices A and V are dense and large, and V is not diagonal....

This plugin lets you keep the awesome Lightbox 2-functionality, but sheds the bulk of the Prototype Framework and Scriptaculous Effects Library.Warren Krewenki ported Lightbox over to jQuery and this plugin is mostly a wrapper to his work. It provides an admin panel for configuration, (optional)...
