Hello! I can differentiate a non-single valued data using Origin-5. However, if I try to use Origin-6 Professional, I get wrong values of the derivative. Perhaps, the differentiation is correct for the single-valued data (still Origin6.0 try to round the corners at differentiation WITHOUT SMOOTHING), but I need to differentiate the double-valued functions.
I am very upset with Origin6-Prof., because I always have to go back to the origin 5.0, which I have only in Japanese. Here is the example: two last columns are derivatives calculated by Origin 5.o and Origin 6.0, respectively.
x f(x) f'(Or5.0) f'(Or.6.0 Prof.)

How can I make the derivative calculated
with Origin6.0 equal to that with Origin5.0 ?

Hi Alex,

Thank you for your report of this problem. I was able to verify it and have reported it to our developers for remediation. Unfortunately some code that was added to support data masking introduced this error for multi-valued functions (only). The solution is not trivial and requires new code so I am unable to provide an easy work around at this time.

If you have other un-resolved issues with Origin 6.0 I would encourage you to contact your Technical Support provider. They may have solutions or work arounds for you to try. In any case, I recommend that you apply Origin 6.0 SR4 if you haven't already.

-Gary
