The output is a matrix whose fourth element is 1 while the first three are 0. Since the (n+1)th element of the matrix corresponds to the coefficient of x^n (where n goes from 0 to n), therefore we get the coefficient of x^3 to be 1. Hence, we know that the polynomial which best fits the data is x^3+0*x^2+0*x^1+0 ...

WebJun 12, 2008 · DataFit is a tool used to perform nonlinear regression (curve fitting), statistical analysis and data plotting. What sets DataFit apart from similar curve fitting and regression programs is its ease of use. DataFit is driven by a well-designed graphical interface, so there are no complicated instructions to remember and no programs to write. http://www.scicos.org/examples.html
WebKey features in Scilab Scilab provides the following features: 6 Uniform Random Number generators in grand, including Mersenne Twister by Matsumoto and Nishimura. This generator has a large period about 2^19937 so that any simulation is guaranteed to use only a small fraction of the overall period.

WebYou see, the simulated data is obtained from a model whose order is exactly known. However, in case of fitting a curve on data obtained through experiment, the model is an "approximation" of the real system.
