Hi I need to calculate the summation of two matrices, where A(1,1:n) and B(1,1:n) are the considered matrices (vectors). I would be really appreciated if you let me know there is any way to perform such a task in Comsol. Notably, “n” is unknown. For example in Matlab, it is possible to use the “sum” function as, sum(A.B)
Thank you for your time and consideration.
