Hi,there,

How can I write the weighting function for SDD? I wish to define the time domain nth differentiation here. Thanks a lot.

I[i, j]] = explicit equation that describes port current in terms of voltage. i refers to the port number. j refers to the weighting function (0,1, or user defined).

If you use for example I[2,0]=_v1/50 there is no weighting function. In order to use the derivative weighting function you need to use for example

I[2,1]=_v1 which means I[2,1]= d(_v1)/dt

I hope this helps.
