Re: Matlab-gams wgdx
But this is because of the model and not the Matlab interface. In the model you reset the values before you solve: R_m$(ord(t)=1) = 0; Q_m$(ord(t)=1) = 0; R_m =4; R_p=1*R(t); Q_m =4; Q_p=1*Q(t); Remove the above and change execute_load 'gams_matlab.gdx'; to execute_load 'gams_matlab.gdx' Q_m, Q_p, R...
