COHSS solver for complex symmetrix linear system Description: The script cohss solve iteratively a complex linear system (1) (B+i*C) (x+i*y) = b+i*c with B and C semi-SPD (SPD=Symmetric and Positive Definite matrices) and B+C an SPD matrix.

Nonsmoothsolve (similar to fsolve), non-smooth & noisy local + some global solvers; works in octave in matlab

The following Matlab project contains the source code and Matlab examples used for nonsmoothsolve (similar to fsolve), non-smooth & noisy local + some global solvers; works in octave . OpenOpt is a free MATLAB Toolbox, which is also run in Octave Particularly, it contains non-smooth solvers ralg (medium-scale, for nVars=1.

2dlda pk lda for feature extraction in matlab

The following Matlab project contains the source code and Matlab examples used for 2dlda pk lda for feature extraction. These are the codes in "A note on two-dimensional linear discrimant analysis", Pattern Recognition Letter' In this paper, we show that the discriminant power of two-dimensional discriminant analysis is not stronger than that of LDA under the assumption that the same dimensionality is considered.
