## Express results using symbolic summation...

Maple

Hi all,

I've searched all over, and I can't figure this out: I'm hoping to have a result expressed in symbolic notation.  For example, if my result is x_1+x_2+...+x_n, how can I have maple express this answer as summation of x_i i=1 to n.

I actually have a matrix, each element of which is a ratio of summations.  In order to more easily comprehend it, I'm hoping to view it in summation notation.

Thanks,

Paul Burkander

## Determining convexity of functions...

I'm an upper-level undergraduate mathematics student, and I'm working on a project to create an algorithm to determine if any function is convex.  My Professor suggested that I post in this forum, to appeal for suggestions.

I hope to apply the algorithm to single or multivariable functions, which have polynomial, power, logarithmic, exponential, trigonometric, or any combination thereof.  The algorithm should work on any predefined domain.
