Algorithm weight matrixes accurately express the complex non-linear relationships of lattice parameters of the two phases with temperatures and phase compositions are obtained based on the back-propagation neural network modeling on the practical values of temperature, phase composition and lattice parameter in various superalloys.

The module has functions of creating weight matrix,global spatial autocorrelation analysis and local spatial autocorrelation analysis,and can be plugged into ArcGIS applications.

Through calculating matrix of initial values, based on original values and state equations of the circuit, and solving the state equations, complete responses (analytic solutions) of the circuit are given.

In the process of its realization, it is necessary to transform the colored graphics on CRT into dual-value matrix, and then to amplify it, furthermore, the amplified lattice of graphics can be shaped by using an appropriate shaping algorism, meanwhile, in order to shorten the matrix operation time and to reduce the internal memory, the shaped graphics should be cut apart.

Fractal image encoding based on distance between difference matrix of blocks;

Reversible data hiding algorithm based on difference matrix of the original image is proposed in this paper, the property of central distributing of the elements in the difference matrix is used to generate the embedding space, the secret information is embedded through modifying the elements of the difference matrix, and this can be mapped to the modification of the pixels of the carrier.

It uses the property that the difference between adjacent pixels is always small and utilizes the difference matrix to do the original image preprocessing,amends and maps the margin matrix to the original image to realize information hiding.

In consideration without increase of computation complexity, we propose an algorithm for gray image segmentation by creating a threshold matrix obtained by global threshold and dynamic threshold that are the FCM clus.
