Hello! I have an error went I run this code. Its show "Error using indexing Too many output arguments." Initially its can be run until I added some this equation that I bold here and its become error. Anyone can help me to fix this error or give some idea to make this equation becomes more simple bcause its only 10% from the whole equation.

I'm guessing that in the expression
you intended
The specific error is because the syntax you used would try to access B.n3 as if it were a field of a structure array.
