3D set with wgdx

GAMS
1

Dear all user,
I want to write a GDX file in MATLAB with wgdx function. This 3D set is:
i1.j2.k3
i1.j3.k2
i2.j2.k3
i2.j2.k4
i2.j3.k2
i2.j3.k4
i2.j4.k2
i2.j4.k3
What should be written in setname.uels?

Hello,

I am attaching some code to do this for two dimensions. If you
understand how it works extending it to three-D is trivial.

Dear Steven;
What is this error?
??? Error using ==> wgdx
Could not write parameter MAP with gdxDataWriteMap

Hello Steve,

I have the following three dimensional table:
Distance Cost Capacity
Node_1 . Node_6 200 20 500
Node_2 . Node_3 400 30 250
Node_3 . Node_7 600 25 200
Node_4 . Node_8 400 30 250
Node_5 . Node_3 600 25 200

Is there a way to generate gdx file of such a table using wgdx without making a separate matrix for each Distance, Cost and Capacity?

Thank you!

Muha
