matlab，sar回波的仿真,....................(sar matlab)

应力应变计算的有限元程序。上课的时候用matlab写的一个代码，其中的刚度矩阵计算，刚度矩阵整合和载荷矩阵计算，都具有通用性，可以参考用于有限元程序设计。(stress and strain of finite element program. When the class was using a Matlab code, which the stiffness matrix, Integration stiffness matrix and load matrix, are generic and can reference for finite element program design.)

this code in used in neural network mlp with back propagation training algorithm and geradian descends algorithm for optimization.in some of this codes I used full propagation algorithm or mlp one layer or two layer with different activation function.this code can be use for prediction or control system by useing neural networks.

This documents describes about Region of interest(ROI) in the image
