The limaps algorithm in matlab

The following Matlab project contains the source code and Matlab examples used for the limaps algorithm. A new regularization method for sparse representation based on a fixed-point iteration schema which combines two Lipschitzian-type mappings: an orthogonal projector and a nonlinear one for sparsity promotion.

Disptable display matrix with column or row labels in matlab

The following Matlab project contains the source code and Matlab examples used for disptable display matrix with column or row labels. Sometimes, rows or columns (or both) of a displayed matrix or vector have different meanings, and it would be nice to display them along with the matrix (instead of, say, remembering that the third row holds a given property of a set of data points).

Find the "i j k" indices of any element number "e" in the 2d or 3d matrix in matlab

The following Matlab project contains the source code and Matlab examples used for find the "i j k" indices of any element number "e" in the 2d or 3d matrix. Many a times it may be required to identify the indices, 'i'(row),'j'(column) and 'k'(plane) values of an element number 'e' % SAMPLE USAGE 1 % [row,column,plane]=findijk(79,[10 10 10]) % row = % 9 % column = % 8 % plane = % 1 % SAMPLE USAGE 2 % [row,column,plane]=findijk(79,[10 10]) % row = % 9 % column = % 8 % plane = % 1 % SAMPLE USAGE 3 % [row,column,plane]=findijk(301,[10 10 10]) % row =

3d bezier curve, in matlab

The following Matlab project contains the source code and Matlab examples used for 3d bezier curve,. %Example: % P=[292 280 321 356; % 196 153 140 148; % -56 75 140 248]; % % t=linspace(0,1,100); % Q3D=Bezier(P,t); % % figure % plot3(Q3D(1,:),Q3D(2,:),Q3D(3,:),'b','LineWidth',2), % hold on % plot3(P(1,:),P(2,:),P(3,:),'g:','LineWidth',2) % plot control polygon % plot3(P(1,:),P(2,:),P(3,:),'ro','LineWidth',2) % plot control points % view(3); % box;.

Unconstrained optimization of a noisy function in matlab

The following Matlab project contains the source code and Matlab examples used for unconstrained optimization of a noisy function. This model was developed for use in teaching optimization in graduate engineering courses. It demonstrates one approach for attempting to find the minimum of noisy functions using gradient-based optimization.

Multi objective optimization using evolution strategies (es) as evolutionary algorithm (ea) in matlab

The following Matlab project contains the source code and Matlab examples used for multi objective optimization using evolution strategies (es) as evolutionary algorithm (ea). This function uses Evolution Strategies (ES) instead of Genetic Algorithms (GA) as Evolutionary Algorithm (EA) in the NSGA-II procedure for multi-objective optimization.

Galerkin method dirivative solver (multiple boundary conditions input) in matlab

The following Matlab project contains the source code and Matlab examples used for galerkin method dirivative solver (multiple boundary conditions input). suppose you have a function u,xx=f.... Well this program will solve this for u(x) given multiple boundary conditions. This is something I did for school in an attempt to get extra credit for going above and beyond. enjoy

Generate random points in multi dimensional space subject to linear constraints in matlab

The following Matlab project contains the source code and Matlab examples used for generate random points in multi dimensional space subject to linear constraints. Generate Random Points in Multi-Dimensional Space subject to Linear Constraints. Algorithm is random walk type. Originally, this is used for MultiStart optimization.
