Question

I have a channel object that contains an array of filterL objects. Each filterL object has some data H. Typing the following into the console . . .

channel.filterL(:).H

gives the output . . .

ans =

   0.0140 - 0.0414i
   0.0133 - 0.0181i
   0.0131 - 0.0095i
   0.0131 - 0.0042i
   0.0131 - 0.0000i


ans =

   0.0140 - 0.0416i
   0.0133 - 0.0181i
   0.0131 - 0.0095i
   0.0131 - 0.0042i
   0.0131 - 0.0000i


ans =

   0.0140 - 0.0420i
   0.0133 - 0.0181i
   0.0131 - 0.0095i
   0.0131 - 0.0042i
   0.0131 - 0.0000i

I cannot simply sum this output like so . . .

>> sum(channel.filterL(:).H)
??? Error using ==> sum
Too many input arguments.

So my question is how do I efficiently reorganise my data so that it can be summed?

Answer 1

Concatenate your data first to change it into one array

[channel.filterL(:).H]
