Please help anyone!!

Hello everyone,

I am new to GAMS and stuck in a problem “loading the gdx file” and trying it since couple of days. The gdx files are being created in matlab. While loading it to gams it showing the error " error 492:symbol not in gdx"
Attaching here the matlab and gams sample code.
Am unable to find out where am going wrong. :frowning:

I know, it can simply be done with “$CALL GDXXRW” as a xlsx read and its working fine too. But, I have a many matrices including 2D and 3D structure that I need in my GAMS code. Interfacing directly from MATLAB will be easier.

But, here am stuck with an error “Symbol not in gdx” .

Anyone please help me with this.

$gdxin BilPrice
$load LambdaB <<<<<< LambdaB is not in billprice.gdx, the symbol in bilprice.gdx is called “bil”

$gdxin ElambdaS
$load SptPrice <<<<<< sptprice is not in elambdas.gdx, the symbol in elambdas.gdx is called “explamdas”

To make it work, change to:

Parameter Bil
$gdxin BilPrice
$load Bil
$gdxin

Parameter Explamdas
$gdxin ElambdaS
$load Explamdas
$gdxin
