本书以有限单元基本理论为重点，以MATLAB程序为平台，以工程实例为背景，介绍 了有限元法及其程序设计方法。 本书讲述结构分析中有限元法的基本原理，单元类型包括平面杆系，空间杆系，平面等 参元，空间等参元，薄板壳单元和厚板壳单元等。内容涉及杆系结构、平面问题、空间问题和板壳问题。以结构线弹性静力分析为主，同时也讲述了结构的振动、稳定和动力响应分析。(This book is the basic theory of finite elements as the key to the MATLAB program as a platform to project examples as the background, the finite element method and its programming. This book describes the structural analysis of the basic principles of the finite element method, cell types including flat bar, space bar, flat isoparametric element, space isoparametric element, sheet shell and thick shell element and so on. Covering the truss structure, flat issues, space issues and shell problems. Structural linear elastic static analysis-based, but also about the structural vibration, stability and dynamic response analysis.)

Wavelet denoising For using this code need to use signal toolbox and general toolbox in your matlab In the first part of this assignment, we asked to obtain a (black-and-white) digital image of size 512 by 512 and then generate noisy image by adding a Gaussian noise but under the condition of having SNR=20dB by select the suitable value of variance for Gaussian noise formula. Second step is performing wavelet denoising using the hard thresholding (Use the db 6 for four levels) in the condition of finding the optimal thresholding value of T in terms of the SNR obtained. It means that, we should find the highest SNR value by finding the suitable value for threshold. Then we asked to do the same process but this time using soft thresholding. Finally for the last part of question one, we should compare the results of the obtained SNR with the recommendations of 3*sigma for the hard thresholding and 3/2*sigma for the soft thresholding.
