Software to find Area under the curve by inputting x and y co-ordinates?

09 September 2016 1 4K Report

Is there any software which can calculate area under the curve if I give the co-ordinates of curve instead of equation?

Will it be valid if there is negative area as well.. When I use Matlab command it gives area negative using traps(x,y)... Is Matlab subtracting the area below x axis or adding it??
