If two points have unequal segments, the Trapezoidal rule would be applied. If 3 points have equal segments, Simpson's 1/3 rule would be applied. If 4 points have equal segments, Simpson's 3/8 rule would be applied. This method gives better estimates than using the Trapezoidal rule alone.

Corrected an error wherein if the size of the data is either 2 by 2 or 3 by 3, it would either result in an undefined integral value (I) or will copy the previously calculated I value. That is, it now evaluates data of 2 by 2 and 3 by 3 sizes.
