Wave equation using MATLAB

Hello, I am trying to solve this wave equation on matlab but I got no luck so far. Please help.

A string of 10 m is pulled upward in the middle to 1 meter and released. The string is not able to move at the two ends. Write the solution of the wave equation(c=1) 

∂u/∂t (x,0)=0

u(0,t)=0

u(10,t)=0

u(x,0)={(x/5,0≤x≤5 and -x/5+2,5<x≤10)}

The Mind-Reading Toolbox, Beta 0.3, reports:

On line 42 of your program, you have a * where you need to have .* instead.

They're taking forever to release that. So some people are not waiting and are taking the matter into their own hands, or uh, minds:

They really should make it where editors/moderators posts are exempt from being labeled spam.
