13 Feb 2013 LBFGSB (L-BFGS-B) mex wrapper Mex wrapper for lbfgsb v3.0 fortan library. L-bfgs-b solves box-constrained optimization. Author: Stephen Becker

Win 7, 64bit system, I have intel fortran compiler and vs 2012 C++ compiler, could you show me how to compile the source code ?

13 Feb 2013 MATLAB interface for L-BFGS-B Matlab interface to the L-BFGS-B nonlinear optimization algorithm Author: Peter Carbonetto

hi, win 7 64bit with intel fortran compiler and winSDK 7.1 C++ compiler,

When compile the c++ codes, all pass except matlabprogram.cpp

How to fix it ? thx

matlabprogram.cpp
matlabprogram.cpp(92) : warning C4800: 'mxArray *' : forcing value to bool 'true' or 'false' (performance warning)

very good, but could you share the source code ?

19 Nov 2014 Gray Level Run Length Matrix Toolbox The toolbox provide useful functions for extract high order run length features Author: Xunkai Wei thomas

few changes todo in the inputparser, if you have only one parameter it should be included in a cell to success at the parser, but in the main function you treat a single parameter as a matrix ...

Thank you for this usefull functions,
i have just 2 "objections" :
- be carefull of iptcheckinput, it will disapear (maybe replace it by validateattribute, and use inputparser matlab object)
- why dont use the standards or graycomatrix (only one direction as output, no cell array, struct for the stats, offset as a direction vector)

Dear Xunkai Wei
Thank you a lot for your useful source code. It helps me so much in my programs.
I am just confused that whether it has some mistakes in the calculation of SRE and LRE.
%1. Short Run Emphasis (SRE)
SRE = sum(p_r./(c_vector.^2))/N_runs;
% 2. Long Run Emphasis (LRE)
LRE = sum(p_r.*(c_vector.^2))/N_runs;
I think we should use p_g instead of p_r ?
