This is an implementation of the calculation of STC value according to ASTM E 413-04. Classification for Rating Sound Insulation.
Input the transmission loss in one third octave bands (dB) and enter the frequency bands and the program will calculate the STC value and produce a graph.
The center frequencies do not have to be exact as the program matches them to the reference contour and applies a tolerance
Advance Resistance Calculator is a tool for calculating the resistances of four band and five band resistors. Basically it is built in GUIDE, which gives friendly user interface and enables the user to enter the resistance band values easily....
For a given function as a string, lower and upper bounds, number of iterations and tolerance Bisection Method is computed.
ToleranceFactor computes the exact tolerance factor k for the two-sided (optionally also for the one-sided) p-content and gamma-confidence tolerance interval TI = [Xmean - k * S, Xmean + k * S], where Xmean = mean(X), S = std(X), X =...
It's a function that finds the minimum value of a two variables objective function with a deterministic zero order algorithm: simplex method.
The input variables are: -fun: inline function of the objective function
The Matrix Function Toolbox is a MATLAB toolbox connected with functions of matrices. It is associated with the book Functions of Matrices: Theory and Computation and contains implementations of many of the algorithms described in the book. The...
This submission contains VERT2LCON and LCON2VERT, which will find the linear constraints defining a bounded polyhedron in R^n, given its vertices, or vice versa. They are extensions of Michael Kleder's VERT2CON and CON2VERT functions that can...
The function (written entirely in MATLAB) allows the selection of connected pixels whose colors are within a defined tolerance of reference pixels.
This program tests an input matrix to see if it is a Euclidean distance matrix to within a user-specified tolerance. If not, it reports why and returns the closest EDM in the sense of Schoenberg.
ELLIPTIC12i evaluates the Incomplete Elliptic Integrals of the First, Second Kind and Jacobi's Zeta Function for the complex value of phase U. Parameter M must be in the range 0 <= M <= 1.
[Fi,Ei,Zi] = ELLIPTIC12i(U,M,TOL)
Calculate minimum of single variable function using 3-point search Usage: estimated_min=three_point(sfun,a,b,tolerance) sfun: Symbolic/String function a: Inferior Limit b: Superior Limit tolerance: Tolerance Range
This code uses conjugate gradient method to solve the linear system Ax= b, where A is symmetric and banded. A is first stored in a compactstorage mode, using the function "compactstorage", and then conjugate gradient...
This function finds the velocity of a 2-dimensional planar wave from at least 2 sensors, by specifying its location (x,y) or (lon,lat) and its respective arrival time.
It returns the speed and direction (or tracking if coordinates were...
It finds the minimum of a n variables function with the Particle Swarm Optimization Algorithm.
% The input parameters are: % -func: it's the objective function's handle to minimize % -numInd: it's the number of the swarm's...
You can solve non-linear systems of 3 variables. Only write "newtonv1" on the command window. Then write the 3 equations, the number of iterations y the precision tolerance. The partial derivatives for the gradients are calculated by the...
This submission is a set of m-files to demonstrate how to take a simple numerical derivative and Hessian of an arbitrary function. Each step in the code is documented. There is a test script included which computes the numerical Hessian of a test...
A Graphical User Interface (GUI) has been developed to solve the Falkner-Skan equation. This famous nonlinear third order Falkner-Skan equation on infinite interval describes several fluid dynamic problems under varying the value of two constant...
COPL = ISCOPLANAR(X,Y,Z,TOLERANCE) takes input arguments x,y, and z as column vectors; TOLERANCE is optional.
COPL = ISCOPLANAR(x) takes an n x 3 input argument in the form [x1 y1 z1;x2 y2 z2;...;xn yn zn] The optional...
It is a Matlab function that determines the zero of a regular real function.
zero=newton_raphson(function,error)
The function has two input variable: 'function' is a string that represents the function of which find the...
The code implements the algorithm as given in Chen et. al 1991.It takes max tolerance from the user.It selects Ms significant regressors from the total M regressors. Unfortunately, the error obtained after training the RBF network isn't as... |
