使用MATLAB对RGB图像进行同态滤波，滤波函数选用高斯滤波器和Logistic曲线(Selection of Gaussian filter using MATLAB RGB image homomorphic filtering, filtering function and Logistic curve)

墙角在对流边界情况下的温度场模拟计算程序。用户输入墙角两侧的流体主流温度，对流换热表面传热系数，设定墙角以及计算网格尺寸后，程序可以通过迭代求解墙体的温度场并以矩阵和三维图像的形式输出。(A simulation program for the temperature field of the wall corner under the convective boundary condition. After entering the mainstream temperature of the fluid on the sides of the corner, the heat transfer coefficient of the convection heat transfer surface, the setting of the wall angle and the mesh size, the program can solve the temperature field of the wall iteratively and output it in the form of matrix and three-dimensional image.)
