The program RANDOM_WALK_2D_PLOT plots the trajectories of one or more random walks. The program RANDOM_WALK_2D_SIMULATION plots averaged data for any number of random walks that each use the same number of steps. The data plotted is the average and maximum of the distance squared at each time step. The average distance squared should behave like the number of time steps.

Sliding Sum Averaging Filter Smoothes data by sliding it past itself, one sample at a time, and summing. The length of the output is the same as the length of the input. The output will be normalized. Equivalent to a moving average (lowpass) filter, but more efficient.

Create linear sweep excitation.

一维分形维数的计算，计盒数，看着好才发上来的(One-dimensional calculation of the fractal dimension, box-counting the number was made up to look good)

image processing central moments also called as Hu s moments and zigzag scan program

这里用的是正交多项式变换法 实现两幅多聚焦图像的融合(Used here orthogonal polynomial transformation method is to achieve more than two-focus image fusion)

A matrix of symbolic elements is reasonably useful for many analytic linear algebra applications, and for analytic vector, matrix and tensor differentiation. This function produces a matrix of arbitrary dimension of symbolic elements that are indexed by their position in the symbolic matrix for ease of reference. EXAMPLE >> M = symMat([2 2], m , real ) M = [ m11, m12] [ m21, m22] >> class(M) ans = sym >> det(M) ans = m11*m22 - m12*m21
