This code uses conjugate gradient method to solve the linear systemAx= b, where A is symmetric and banded. A is first stored in acompactstorage mode, using the function "compactstorage", and thenconjugate gradient method is applied to the compactly stored matrix.Input: A, initial guess x, vector...

We present a Matlab toolbox which can solve basic problems related to the Total Least Squares (TLS) method in the modeling. By illustrative examples we show how to use the TLS method for solution of:- linear regression model- nonlinear regression model- fitting data in 3D space- identification of...

To calculate an area S(A) of a figure A, bounded by a Jordan curve (which in our case is constructed by a cubic splineapproximation) the Monte Carlo method is applied
