Ventana software support forum

I am just wondering, does anybody know how to carryout matrix multiplication in Vensim, without writing the whole equation manually?

Suppose you have three dimensions x,y,z which are implemented as subscripts. Then

matrix product of a and b[x,z] = SUM(a[x,y!]*b[y!,z])

if x,y and z are not distinct dimensions you will need to create an equivalence subscript.

Thanks a lot.
