Dear all,
I am trying to define a spline for a set of data whose derivative goes to zero after a certain set of time. Then I have to use this spline for interpolation in a for loop using ppval. But the problem is that in reality the derivative of the spline approaches to zero but the defined spline goes on increasing. At the start both values are matching, the actual and the spline but at larger values the deviation is greater.
In actual scenario, at approximately 20 value at the x axis, the y axis value keeps on increasing, but after that the y value remain approximately constant, even if x-axis value goes to infinity.
Thank you for your response in advance.
