excel - VBA looking for error values in a specific column -

- 

sub macro9() dim lreturnvalue boolean  lreturnvalue = iserror(sheets("lookup addition").range("a:a").value)  if lreturnvalue = false     = msgbox("there no errors", vbokonly) else     = msgbox("there errors", vbokonly) end if  end sub

i little confused iserror(customfunction()) syntax should be. how tell check every cell in the range?

counting errors in range doesn't require looping (which can slow if range large) or vba.

just add worksheet function cell somewhere. if don't want user see cell, can hide row/column/sheet.

=sumproduct(iserror(a:a)*(1=1))

if still want pop-up box user, vba be:

sub counterr()        msgbox "there " & activesheet.range("b1").value & " errors"   end sub

make sense?

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2
