Sum of the components of a variable - Modelica

I have defined a variable which has two elements y[i,j]. How can I sum all the components of this variable in Modelica?

Thanks

Solution

  • This is very simple:

    sum(y)

    See also 10.3.4 Reduction Functions and Operators in the modelica specification.

    Note: Your example does not have 2 elements, but i*j. There are 2 dimensions, with i elements in dimension 1 and j elements in dimension 2. See chapter 10.1 Array Declarations for details.
