Why just email? Some of the posts to MATLAB Answers look just like this.

Sir,
Please consider that problem.
a) Write a Matlab function that produces a fourth-order accurate Lagrange interpolation f4 (x) for a function f in the point x , given the points x0 , x1 , x2 , x3 , x4 and the values f(x0 ), f(x1 ), f(x2 ), f(x3 ), f(x4 ) .
b) Given f(?1/2 ) = ?1, f(?1/6 ) = ?1/2 , f(0) = 0, f(1/6) =1/2 , f(1/2 ) =1, show that these values indicate that f could be an odd function. Use your Matlab function to find the fourth-order interpolation at x=1/3 and the fourth-order extrapolation at x =1. Would the extrapolation be accurate (explain)? "

And did you consider it?

@Matt
No, I didn't. I at least want "Hello" and "plz." Also, the sender did not say that it was "Urgnt," and the message lacked the obligatory minimum of 5 exclamation points to motivate me.
@Sean de
Nostalgic? Yes. Inspiring? No.
