[casper] Question about complex_addsub block

Hi Well I feel a little bit stupid asking this, but from the addsub block: Adds and subtracts the complex inputs. If a = w + ix, b = y + iz then a+b = (w+y)/2 + i(x-z)/2 and a-b = (x+z)/2 + i(y-w)/2 Why it does it like this? Shouldn't it be simply: a+b = w+y + i(x+z) a-b = w-y + i(x-z) I

Re: [casper] Question about complex_addsub block

Hi, Franco, I can understand your confusion! This block is very unusual. In all fairness, that bock does what it says it will do, but it is unclear what it’s intended purpose is. I think it really computes "a+(b*)" and "-i(a-(b*))". It does not appear to be used by any other blocks in the

Re: [casper] Question about complex_addsub block

Thanks! That's a relief, for a moment there I doubted my high school math knowledge. Just out of curiosity, how do you check if a block is used by another block in the library? Franco On 10/03/2016 06:14 PM, David MacMahon wrote: Hi, Franco, I can understand your confusion! This block is

Re: [casper] Question about complex_addsub block

I just went into the casper_library directory and ran "git grep -l complex_addsub". I now realize that maybe the block is used by a block in a .slx format file which that command will not find. So maybe it is used. To be sure, one would have to use some form of the "find_system" command at
