widn turbine generator system model for study

this programme define a circuit-based simulation model for a PV cell in order to allow estimate the electrical behavior of the cell with respect changes on environmental parameter of temperature and irradiance

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

多载波天线下的自适应调制，很好的体现了系统的性能，可以做为源文件(Under the adaptive antenna multi-carrier modulation, well reflects the performance of the system can serve as a source file)

改程序为火星探测巡航段的轨迹优化程序，采用庞德里亚金极大值原理对轨迹进行优化(Change the trajectory of Mars exploration program for the cruise phase of optimization procedures, using the maximum principle Pound Calabria gold trajectory optimization)

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
