The function generates sequency(Walsh) ordered Hadamard matrix useful for image processing, signal processing, genetic algorithms etc.
MULTIPROD is a powerful, quick and memory efficient generalization for N-D arrays of the MATLAB matrix multiplication operator (*). While the latter works only with 2-D arrays, MULTIPROD works also with multidimensional arrays. MULTIPROD...
A C++ matrix class for creating matrix objects and easily performing elementary operations between matrix objects including addition, subtraction, multiplication, transposition, and trace.
Because the matrix multiplication is associative; the product can be carried with different order, leading to the same result up to round-off error, MMTIMES usings "optimal" order of binary product to reduce the computational effort...
This toolbox provides several state of the art high order run length matrix statistics for image analysis.
Currently supported features are:
1. 0,45,90,135 direction run-length matrix 2. Fully vectorized coding style
Three case studies: random matrix theory for estimation vs. cross-sectional model for attribution; hedging based on full-repricing instead of Black-Scholes deltas; heuristcs for best K attribution/hedging factors out N
To walk through...
X = POWERM_PADE(A,P) computes the P'th power X of the matrix A, for arbitrary real P and A with no nonpositive real eigenvalues, by the Schur-Pade algorithm. [X,NSQ,M] = POWERM_PADE(A, P) returns the number NSQ of matrix square roots computed and...
SpeedyMaths provides timed maths problems of addition, subtraction and multiplication for children to practise their basic maths skills.
In this project i have coded (C++) Gauss elimination matrix solver for cfd applications
I created this class of zero-indexable arrays purely as a fun OOP exercise, in reaction to various Newsgroup threads inquiring about zero-indexable matrix types for MATLAB. Even though I've gone to the trouble to overload many methods for the...
This function generates the 2D Walsh or Hadamard Transform of a matrix. Where the Walsh Transform uses the sequency ordered matrix and the Hadamard the natural/hadamard ordered matrix. The paley ordered transform is not yet...
The result will be displayed in a matrix format.
For uniform distributions,the values returned by the MATLAB function rand() are multiplied by (b-a), then added to a.
For normal distributions the output of randn() is...

MMTensor is a collection of documented MATLAB scripts for micromechanical computations. It contains methods for basic computations with tensors in matrix notation, for computing and analyzing fabric tensors, and for (limited) inclusion...
This test has been implemented according to Jennrich (1970). It is a Chi2 based test for overall correlation matrix eqality, for two independent correlation matrices. It computes the Chi2 value, degrees of freedom and the p value. Three files are...
This directory contains MATLAB functions for the fast multiplication of a Toeplitz matrix times a vector. By using these routines you can avoid storing the entire matrix (using two vectors of lenght n rather than a matrix of size n*n), and also...
A set of blocks for manipulating 3x3 and 4x4 matrices. In versions of Simulink prior to R12, matrices were handled in row-major form, thus the need for special blocks to handle matrices. Although Simulink can now handle arrays as signals, some... |
