[data, plot_title] = ssbin2mlab(filename, desired_variable) reads a Binary Smartspice RAW file 'filename' and extract the variable(s) of interest from 'desired_variable' using the file's...
The method uses finite differences to solve Laplace equation and matrix inversion to solve the resulting system of linear algebraic equations. The rectangular plate has both dimensions set equal to unity. Each dimension is discretized and the...
SYNTAX: B = fulltosparse(A)
A = full 2-dimensional double matrix B = sparse 2-dimensional double matrix version of A
This example demonstrates how to populate a sparse matrix. For the purpose of this example, you must...
Complex step differentiation (CSD) has many advantages in efferency and accuracy over finite difference approaches (central, forward and backward). This code demonstrates how the Jacobian matrix of a given function at the reference point can be...
Generates complex generalized gaussian random variables with augmented covariance matrix Ta = [2*s 0; 0 2*s]; and shape parameter c, where c = 1 corresponds to the Gaussian case. x = cggd_rand(c,s,N) generates a vector 1xN of...
Computes triangular rvs from an set of input random numbers given min, max and mode values using the inversion method.
This function can handle single value, vector and matrix input.

AML++ is a matrix library which mimics most Matlab/Octave features and functions. It offers many different matrix classes (both real and complex including generic dense and sparse matrices, upper/lower triangular, symmetric, Hermitian and band).
The unit MATRIX offers some of the most important operations to manage and process two-dimensional real-valued and integer matrices. The object oriented approach of the unix MATRIX hides all the stuff dealing with array addressing and memory...

This is a templated library of numerical base classes which implement basic data structures like complex numbers, dynamic vectors, static vectors, different types of matrices like full matrices, band matrices, sparse matrices, etc. and also...
The library supports only basic matrix operations, not being suitable for large matrices.
It has been tested with: Borland C++ 5.0 (both 16 and 32 bit); Borland C++ 5.5; C++ Builder version 1.0, 3.0, 4.0 and 5.0; MS...
This DHTML script renders the Matrix effect on any short piece of text. It works in both IE4 and NS6 , and downgrades well with the rest.
It will help you to make a N-point Paired matrix for FFT.
This is a simple program written so the equations look like classical matrix equations and it solves the voltage out of the standard current driven loop filter. This is intended to be used in some future PLL analysis program, but it outlines the... |
