So long as you define the samples as X := [...] and Y := [...] that should work.

Just did it of the top of my head so I'm sure there's a better way but that should work. (May wanna check it against known values though).

Also ignore the standard maple error... -0.9999999997 = -1 basically. - Apr 22nd 2010, 07:29 PMdwsmith
This what happened when I attempted the calling procedure.

> Pearson:=proc(A,B):

print(`output redirected...`); # input placeholder

Error, unterminated procedure - Apr 22nd 2010, 07:48 PMdwsmith
