hilbert peono order selectionIn 1890, Peano discovered a densely self-intersecting curve that passes through every point of the unit square. His purpose was to construct a continuous mapping from the unit interval onto the unit square. Peano was motivated by Georg Cantor's earlier... Platforms: Matlab

Well, i made this function some time ago and its purpose was to fit the Universe of the Greek stock market. After having grabbed my information to some matrices, vectors, god knows what, i decided to use it to price interest rate derivatives! I wont tell how, but you might as well try it as...

Let us suppose a set of non-linear equations in the formF(m) = d(m,d are vectors, F is a vector function of vector argument). ANNI tries to construct suitable numerical approximation for inverse projection of d to m, i.e. to find numerical form ofG(d) = m.Such mapping may not exist in general,... Platforms: Matlab

When producing a spectrum with fft.m there is no build-in m-file to find the corresponding y-axis. Example; if you want to plot the real Fourier coefficients of a signal (y) with corresponding time (t), write 'plot(freqspace(t),real(fft(y)))'. Created while finding derivatives in the Fourier...

DATCOM has been widely used for preliminary estimation of an aircraft's aerodynamic coeficients and its stability derivatives. Given an aircraft configuration declared in an ASCI text file, DATCOM will easily provide the estimation of the aircraft's aerodynamic coeficients and its stability... Platforms: Matlab

Like the finite difference method, the Taylor Series Least Squares method can be used to estimate derivatives. The TLS technique can be used to estimate derivatives from scattered or unstructured data. The Hermite Taylor Series Least Squares technique augments the TLS approach with information...
