Magento set template variable programatically -

-

i need able send transactional emails include conditional sentence. want include sentence in order confirmation emails orders contain products. there plenty of examples of how use conditionals within transaction emails based on built in variables, want base conditional on own variable i'll create programatically within own extension.

the mailer class mage_core_model_email_template_mailer have public settemplateparams method, method calls base classes setdata method, if access method set own parameters overwrite core template parameters nessesary show contents of basket.

any ideas on how achieve appreciated.

you should create new order attribute save conditional sentence. can access attribute in transactional email template via {{htmlescape var=$order.getyourattribute()}}

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...
