How are erf(.), Q(.), and Gaussian Tails Related?

This video saved my ass in Estimation, Detection and Classification!

I'm glad it helped!

I've been binging the videos on this channel, they helped me so much crystallising many concepts. thanks!
Why is erf the default function offered by computer stat libs instead of Q? Is it easier to compute?

[@iain_explains]

Thanks. I'm so glad you like the videos. I really don't know why erf is the default function. I've often wondered this myself. Perhaps because statisticians and computer scientists are most often interested in variation around the mean (erf function). Whereas telecommunications engineers are more interested in deviation to far away values which cause detection errors (and so are drawn more to the Q function).

Thanks. I'm glad you liked it.

What if I have an exponent with positive coefficient and limits from 0 to variable

[@iain_explains]

Well, that's not a Gaussian, so it'll need some other approach.

Please how to represent the function using matlab

[@iain_explains]

I'm not sure what you're asking sorry, because the "erf(.)" function in the video is exactly how you write it in Matlab.
