Sets and 3D tables Matlab to GAMS IWGDX

[Archiver]

Dear all,

My problem is with getting a main set generated randomly in Matlab with other data including 3D table as GDX using IWGDX in Matlab.

set
x /1*5/,
y /1*3/,
t; 'Randomly generated in Matlab'
parameter
A; ' Randomly generated in Matlab'

$GDXIN gdxdata
$LOADIDX t A
$GDXIN

Now A is a table [A(x,y,t)] which 3D
I tried transferring by

iwgdx('C:\gamsdir\projdir\gdxdata','t','A') and
,'A:3')
still getting errors
I was getting errors with the 2D but after using 'a:d' |d--> dimension solved it.

Thanks

I was thinking if having the upper bpund of the set (t) as a scalar (tt) and then set t/1*tt/; but getting error 764 Could not extract number in * list

Any suggestions?
Thanks

Getting error 832 Can only load parameters and scalars.

Also getting 833 Can only load parameters with proper domain for the tables


Now I'm using WGDX to write sets. Better but still getting error 832 Can only load parameters and scalars

Although writing it as follows in Matlab:
tt.name='t';
tt.uels={1:T};
tt.type='set';
and parameter A then
wgdx('C:\M2G',tt,AA)

and
set t;
parameter A(t);
$if not set gdxin $set gdxin M2G
$GDXIN %gdxin%
$LOADIDX t A ...
$GDXIN

Please show me the proper way.
Thanks all
