Improving-Dictionary-Learning

建立了一个空间固定曲率和挠率的三维血管模型，并绘制出三维的图像(Created a space for fixed three-dimensional curvature and torsion vessel model, and draws three-dimensional images)

很好的程序，可以直接用。不会出现错误good program good program(a good process, the direct use of it, no errors，good program good program good program)

基于matlab的XFEM简单实现,内有实例，可算裂缝开展(subroutine for XFEM)

一份非常不错的MATLAB资料，值得一看(MATLAB, a very good information, worth a visit)

matlab在土木工程领域运用，有限元程序，求解振型和频率，给出了阵型图。程序已模块化(matlab use in the field of civil engineering, finite element program, to solve the vibration modes and frequencies are given in Figure formation. Program has a modular)

bp_innerloop.m Inner loop of the backpropagtion learning algorithm. One hidden layer. Uses tanh as the transfer function. Uses the following global variables for input and/or output: Inputs1 - input patterns Desired - desired output patterns LearnRate - learning rate parameter Momentum - momentum parameter DerivIncr - increment to the derivative of the transfer function (Fahlman s trick typical value 0.2) Weights1 - first weight layer (updated by this routine) Weights2 - second weight layer (updated by this routine) deltaW1 - initialize to 0 before first call deltaW2 - initialize to 0 before first call TSS - total sum-squared error (set by this routine) Recurrent state

增量式PID控制算法Matlab仿真程序 设一被控对象G（s）=50/(0.125s^2+7s),用增量式PID控制算法编写仿真程序（输入分别为单位阶跃、正弦信号，采样时间为1ms，控制器输出限幅：[-5,5],仿真曲线包括系统输出及误差曲线，并加上注释、图例）。(Incremental PID control algorithm Matlab simulation program to set up a controlled object G (s) = 50/(0.125s ^ 2+7s), with incremental PID control algorithm simulation program written (unit step input, respectively, sinusoidal signal sampling time is 1ms, the controller output limiter: [-5,5], including simulation system output and error curve curves, plus notes, legend).)

说明：  这是一个创建BP神经网络的matlab源代码，包括BP神经网络的创建、曲线拟合等内容。对初学者很有帮助(This is a create BP neural network matlab source code, including the creation of BP neural network, curve fitting and so on. Very helpful for beginners)
