The new interface merges the read and write routines of GDXMRW and the original MATLAB/GAMS interface into one system with three routines:
Placeholders for the deprecated routines (from version 1 of GDXMRW) readgdx.m and writegdx.m are also provided but the user is encouraged to switch to the new, more efficient rgdx and wgdx routines. The routine "gams" is not backwards compatible: calls of the old form:
must be replaced by (for example)
sQ.name = 'Q'; sQ.val = Q; gams('qp',sQ);
(due to a change by Matlab in the mex interface). There is also a requirement for a "header" line in the GAMS file if you are using output parameters and some changes to the syntax within the GAMS file are needed.
From version 23.4 of GAMS onwards, the MATLAB facilities are provided within the GAMS distribution (download current GAMS distribution) for Windows, Mac and Linux platforms. Simpler installation procedures are provided in the documentation in the GAMS distribution or online at: (GDXMRW new version installation and documentation).
