这次是对添加水印的图像中添加一种高斯噪声的matlab程序(The watermark image is added to add a Gaussian noise process)

In mathematics, the Fibonacci sequence is the following infinite sequence of natural numbers: The first element is 0, the second is 1 and each remaining element is the sum of the previous two: Each element of this sequence is called Fibonacci number. This sequence was described in Europe by Leonardo of Pisa, XIII century Italian mathematician known as Fibonacci. It has numerous applications in computer science, mathematics and game theory.

基于三角形单元有限元原理，计算桁架系统在外力作用下，各节点位移与单元应变。主程序BLOCKMAT.m，从输入文件中读入结点个数，单元个数，结点荷载个数，受约束边界点数，弹性模量，泊松比，厚度，单元定义数组，结点坐标数组，结点力数组，约束信息数组。输入文件int.txt不同参数代表不同的桁架结构。(on the basis of the principle of triangle finite element calculation truss system under the action of external force, displacement of each node and element strain. MAIN program MAIN. J m, read from input file node number, cell number, number of nodal load, a constrained boundary points, elastic modulus, poisson s ratio, thickness and unit defined array, node coordinate arrays, nodal force array, array constraints information. Input file int. TXT different parameters represent different truss structure.)

说明：  用matlab编写的几个小程序，有关于矩阵的计算，神经网络的训练。数据的输入输出等。(Matlab prepared with a few small procedures have on the calculation of the matrix, neural network training. Such as data input and output.)
