Software Listing: Non Linear

The non-linear regression problem (univariate or multivariate) is easily posed using a graphical user interface (GUI) that solves the problem using one of the following solvers: - nlinfit: only univariate problems. - lsqnonlin: can deal with multivariate problems (more than one dependent fitting variable, ydata is a matrix). - patternsearch: this solver is useful to obtain a good start point, before using nlinfit or lsqonolin; this way, the global minimum is determined easier. Data is introduced in the GUI as vector or matrix from the workspace. The model to be fitted must be written in an M-file in vectorized form: ypred = model(x,xdata) ypred is a column vector (univariate problem) or matrix (multivariate problem) with the model response (observations in rows).

solvesimul.m can be easily adapted to solve more equations but as it stands it will solve 2 unknowns in 2 equations (1 non-linear and one linear). To solve equations of this form... a*x + b*y = A (1) a1*x^2 + b1*y^2 = B (2) ...with fsolve (used by solvesimul.m) you need to rewrite them so that they equal zero. so (1) and (2) become a*x + b*y - A = 0 (1a) a1*x^2 + b1*y^2 - B = 0 (2a) then using a nested function approach (there are many other ways) you can solve some system of non-linear equations. An example, 2*x + 3*y - 8 = 0 4*x^2 + 5*y^2 - 24 = 0 At the MATLAB command-line prompt you run the 'solvesimul' m-file function with the correct arguments i.

symsolvesimulv2.m can be easily adapted to solve more equations but as it stands it will solve 2 unknowns in 2 non-linear equations (can be linear too or a mixture). Big change: It now has data input integrity checking. At the MATLAB command-line prompt you run the 'symsolvesimulv2' m-file function with the correct vector arguments i.e. exponents, coefficients and constants in the equations in the appropriate order. >> help symsolvesimulv2 solves a system (a pair) of non-linear or linear equations or a mixture, returning a n x 2 column solution vector for x and y. The first parameter is a row vector (1 x 4) of exponents used in both equations.

Let us suppose a set of non-linear equations in the form F(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 of G(d) = m. Such mapping may not exist in general, and therefore ANNI constructs data/model subspaces covered by population of individuals, for which the inverse G hopefully does exist at least locally. Size and shape of the population are determined adaptively by using empirical rules during the inversion. Numerical approximation of G is achieved by (i) linear regression, (ii) linear prediction ('Kriging') and, (iii) radial basis function network.

As its name suggests, Non-linear arithmetic property checker via Bernstein polynomial is a handy tool for checking certain polynomial constraint problems.

You can use the examples that the application comes with or create your own by specifying the variables, the coefficient of the polynomial and the bound for each variable.

Engineering Suite is a small, easy to use application specially designed to offer you a program to help you solve non-linear equation system as well as linear equation system in which you write the equations and the program solves them numerically.

Please note that to solve a non-linear equation system you have to solve a linear equation system in the process. This fact is important because the resolution of linear equation system is very easy compared to the resolution of non-linear equation system and the program development was in order to make the resolution of those equation easier to users.

Scientific tool/solver to solve single variable non-linear equations (NLS). The app can compute multiple roots of a NLS. The app has two different options to compute the root of NLE viz. (a) general (b) specific. General search option gives the root of NLS without any user specified limits (should be used for NLS with single roots).Specific search option gives the root within the limits specified by the user (should be used for NLS with multiple roots to find multiple roots with different limits).The app has a very rich and user-friendly UI (user interface). The results can be sent to any e-mail id by using “Send e-mail” option in main menu.

As we move to new digital era, we tend to rely on tireless machines in almost every aspect of our everyday life. Computer is an infinite source of creativeness and a perfect tool for any digitized activity, from collecting photos to modeling complex systems.There is another aspect of computer usage that was the initial task for the device called 'computer' - to compute. Various calculations and some serious math is exactly what computers were created for.These days, there are many things that require mathematical modeling: from exchange rates prediction to engineering and financial planning. That is exactly the point where smart people start looking for math software that is flexible enough to handle solving various tasks that may be described using formulas and equations.
