Train a two layer neural network with a recursive prediction error
% algorithm ("recursive Gauss-Newton"). Also pruned (i.e., not fully
% connected) networks can be trained.
%
% The activation functions can either be linear or tanh. The network
% architecture is defined by the matrix NetDef , w ...
IML package provides efficient routines to solve nonsingular systems of
linear equations, certified solve any shape systems of linear equations,
and perform mod p matrix operations, such as computing row-echelon form,
determinant, rank profile, inverse of a mod p matrix.
This project features a complete JPEG Hardware Compressor (standard Baseline DCT, JFIF header) with 2:1:1 subsampling, able to compress at a rate of up to 24 images per second (on XC2V1000-4 @ 40 MHz with resolution 352x288).
Image resolution is not limited. It takes an RGB input (row-wise) and outp ...
Traveling Salesperson Problem
Our branch-and-strategy splits a branch and bound solution into two groups:
one group including a particular arc and the other excluding this arc.
1.Each splitting incurs a lower bound and we shall traverse the searching tree with the "lower" lower bound.
2.If a const ...
Playfair Cipher
1.not even the large number of keys in a monoalphabetic cipher provides security
2.one approach to improving security was to encrypt multiple letters
3.the Playfair Cipher is an example
4.invented by Charles Wheatstone in 1854,but named after his friend Baron Playfair
Playfair Key M ...
The code performs a number (ITERS) of iterations of the
Bailey s 6-step FFT algorithm (following the ideas in the
CMU Task parallel suite).
1.- Generates an input signal vector (dgen) with size
n=n1xn2 stored in row major order

list of matlab m-files on matlab 7.0. learning , support vector machine and some utility routines : autocorrelation, linearly scale randomize the row order of a matrix
This m file hide an image jpeg,png in another jpeg,png image.
The height and width of the secret image is in LSB of 1st 32 pixels of 1st row of the cover image.This helps in the recovery of secret image.
The secret image must be smaller than cover image.A message box will appear with a numbe ...
I originally wrote this program as an exercise for learning JAVE. Gomoku game is well-known in many countries and every country calls it differently. The winner is the first player to get an unbroken row of five stones horizontally, vertically, or diagonally.
