Hi All,

I am trying to work out the 'A' weighting values for sound levels, I have the calculation working, but I would like to simplify the total power levels, by either summation or a loop function. I know how to use summation, but cant get it to work on this.

How's this? Using vectorize() function to apply operations to each element in a matrix.
