已知弹性模量计算超声波(横波)穿透固体与液体界面时的能量分配算法。(Ultrasonic elastic modulus (shear wave) to penetrate the solid and liquid interface energy allocation algorithm.)

Calculate the eigenvalues of many 3x3 real symmetric matrices.(Calculate the eigenvalues of many 3x3 real symmetric matrices. Computation is non-iterative, based on fully vectorized matlab matrix operations, and GPU computation is supported. It is fast and efficient for processing a number of 3-by-3 matrices at once. This code particularly suits tensor/Riemannian calculus in 3D, visualization/analysis of volumetric tensor images, image Jacobian/Hessian analysis, stress/tensile strength computation on tensor fields, three dimensional diffusion processes, determining the rotation axes of a motion field, etc....)

将像素数据写成一幅PPM格式的图片，像素数据为灰度图的数据，附件里有一个图像数据，宽150，高90，共100帧(The data will be written in a grayscale image PPM format, the program is written in matlab, the file contains a grayscale data.)

Objective of the program is to solve for the steady state voltage distribution of the inside region of a microstrip and then using that obtain the electric field distribution in the region using quiver plot. The microstrip comprises of a region given by 0<x<7 units and 0<y<2 units in the coordinate system bounded by four capacitor plates on all the sides of the region. The region comprises of a material with relative permittivity 1 from 0<y<1 units and a material of relative permittivity 9.6 from 1<y<2 units. The microstrip extends indefinitely in the z-direction. The sides of the region are given Dirichlet boundary condition. A horizontal microstrip line is placed at the center of the region. The microstrip is excited with a voltage of 1 Volt and all surrounding plates are maintained at 0 Volts.
