acpd_isu

This repository contains the MATLAB code for the problem of nondestructive testing of metal material using alternating current potential drop measurement. The estimation of the conductivity and magnetic permeability are done by solving a linearized 1D inverse problem.

cageo-2016-18-r1

Matlab files for solving the inverse geothermal problem as described in the paper: An efficient regularization method for a large scale ill-posed geothermal problem, Computers & Geosciences, 2017

color-deconvolution

Color Deconvolution Algorithms for H+E images

colordeconvolutionmatlab

A Matlab implementation of Ruifrok's color deconvolution algorithm.

comparision-of-linear-solvers-for-solving-a-2d-diffusion-equation

Solving a 2D diffusion equation using finite volume methods requires one to invert huge sparse matrices. We compare iterative methods such as Gauss-Siedel method, line-by-line TDMA method, Steepest gradient method and Conjugate gradient method.

globalbioim

A unifying Matlab framework for the development of reconstruction algorithms (solving inverse problems) in computational imaging

gmres-cg-cgls-lsqr

The fourth assignment breaks into three parts. First part is to use convection-diffusion test matrices from Assignment 1 to test the effect of ILU preconditioned on GMRES convergence. Second part is to test the numerical differences on CG, CGLS and LSQR by solving normal equation AT Ax = AT b. Also, choosing A by selecting α on L−αI, where L is the finite-difference Laplacian matrix and I is identity. Last part is to find a good preconditioner and solve the least square problem by LSQR.
