菲涅尔透镜的matlab程序 对于衍射光学元件设计有重大帮助(Fresnel lens matlab program for diffractive optical element design has significant help)

介绍用matlab进行有限元计算的国外经典著作，前面重点介绍了有限元的相关内容，后面重点讲解了如何利用matlab的工具箱实现有限元的计算。(This book gives a background treatment of the Galerkin method in Chaps. 2–4. Topics such as developing weak formulations as prelude to solving the finite element equation, interpolation functions, derivation of elemental equations, assembly and sample solutions were treated in these chapters. Chapter 5 gives an overview on the use of the pdetoolbox. Chapter 6 and 7 give different sample problems and their solutions on heat transfer and elasticity in Materials Engineering.)

to understand the Algorithm go to matlab help in page dct2 and idct2 to get the mathematical expression for M = N = 8, we can calculate the most of hard values and save it as LUTs to speed up the execution now compare our special 8X8 functions with the internal general functions use this code: A = int32(100*rand(8,8)) tic for i = 1 : 1000 IDCT_8X8(DCT_8X8(A)) end toc tic for i = 1 : 1000 idct2(dct2(A)) end toc i had built the general functions too, but with low speed (to understand the Algorithm go to matlab help in page dct2 and idct2 to get the mathematical expressionfor M = N = 8, we can calculate the most of hard values and save it as LUTs to speed up the executionnow compare our special 8X8 functions with the internal general functionsuse this code: A = int32 (100* rand (8,8)) tic for i = 1: 1000 IDCT_8X8 (DCT_8X8 (A)) end toc tic for i = 1: 1000 idct2 (dct2 (A)) end toc i had built the general functions too, but with low speed)
