c# - Entity Framework IDENTITY_INSERT ON doesn't work -

-

i have code supposed insert record identity insert on

using (mct_db_archiveentities ent = new mct_db_archiveentities()) {   ent.executestorecommand("set identity_insert [clicks] on");   ent.clicks.attach(ck);   ent.clicks.context.objectstatemanager.changeobjectstate(ck, system.data.entitystate.added);   ent.savechanges(); }

i error.

cannot insert explicit value identity column in table 'clicks' when identity_insert set off.

it not supposed work. works if identity insert turned on on same connection real insert. in case 2 different connections can used. make work have maintain own db connection , pass objectcontext's constructor.

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...
