Hello,

I have a sampled data and the sampling frequency is known. Is there any function that can find the area under the implicit continuous curve? MATLAB function quad (to integrate) require the equation of the curve i suppose.

trapezoidal method is less accurate. Is there any function that uses other sophisticated models?
