Area under curve (cell array)

Hi
I have the following cell array and I need to find the area under each vector (curve) [columns 1 and 2] between two points [columns 3 to 6]. Each vector is composed of number of cells (e.g. the first vector is composed of 39 cells) and each cell is composed to two elements (strain, stress). So I need the area under the curve just between (starin1, stress1) and (strain2, stress2). Please help.

What is the contents of e.g the {1x39 cell} in Strain1? Please explain this again.
