Numerical analysis projects and source code

Triangle problem solver in c

The following C project contains the C source code and C examples used for triangle problem solver. Have you ever seen a problem where you must get the three sides of a triangle to each add to 20 using only the numbers 1-9 once each?? this code solves it and may be helpful for beginners + intermediate programmers as it was for me .

B spline tools in matlab

The following Matlab project contains the source code and Matlab examples used for b spline tools. B-splines is a natural signal representation for continous signals, where many continous-domain operations can be carried out exactly once the B-spline approximation has been done.

Create a matrix which includes every combination of data set elements in matlab

The following Matlab project contains the source code and Matlab examples used for create a matrix which includes every combination of data set elements . This matrix could be used in searching algorithms or optimization process to perform every combinations for each parameters. The code generates a (#Elements)x(#Parameters) matrix and each element is assigned to each parameter individually.

Performs sinc interpolation, and also resampling of a intput waveform in matlab

The following Matlab project contains the source code and Matlab examples used for performs sinc interpolation, and also resampling of a intput waveform . %Interpolating and resampling function, where: % I = interpolation rate % D = resampling location, number of samples to shift % x(n) = input waveform % y(n*(1/I) + D) = output waveform % --includes option smoothing with an exponential % decaying function to reduce Gibbs ringing.

Solves siso mean-square optimal control design problems: a(p)x = b(p)u + f(t) in matlab

The following Matlab project contains the source code and Matlab examples used for solves siso mean-square optimal control design problems: a(p)x = b(p)u + f(t) . Solves SISO mean-square optimal control design problems of the following form: Let the controlled plant is described by differential equation                  A(p)x = B(p)u + f(t), where x - scalar controlled variable, u - scalar control, A(p),B(p) are polynomials of p = d/dt, f(t) - external disturbance with known spectral density Sf=S(s)S(-s)=N(s)N(-s)/(T(s)T(-s)) (N(s),T(s) are Hurwitz polynomials).

Solves constrained minimization problems, some of the variables are restricted to discrete values in matlab

The following Matlab project contains the source code and Matlab examples used for solves constrained minimization problems, some of the variables are restricted to discrete values . fminconset: Solves constrained minimization problems where some of the variables are restricted to discrete values. (Mixed Integer Nonlinear optimization). Based on fmincon from Optimization Toolbox version 2.0.

A primer for finite elements in elastic structures in matlab

The following Matlab project contains the source code and Matlab examples used for a primer for finite elements in elastic structures. This book disassembles the entire finite element method for civil engineering students and professionals, detailing its supportive theory and its mathematical and structural underpinnings in the context of elastic structures and the principle of virtual work.

This collection compute square root free cholesky factorizations of the form a=l*d*l' in matlab

The following Matlab project contains the source code and Matlab examples used for this collection compute square root free cholesky factorizations of the form a=l*d*l' . The m-files in this collection compute square root free Cholesky factorizations of the form A=L*D*L', modified Cholesky factorizations for matrices which may not quite be positive definite, and rank-one updates of the factorizations.

Find polynomial intersections in matlab

The following Matlab project contains the source code and Matlab examples used for find polynomial intersections. Given the coefficients of 2 or more polynomials, this program will return their intersection points be it real or imaginary and the full string representation of these polynomial equations. e.g. 'y=2*x^3+4*x^2+3' Suitable for use with the MATLAB 'polyfit' function
