# Difference between mathematical interpolation and numerical interpolation?

I have a data set of points. This data is not of full points. Instead, I have to generate a python code using tck = interpolate.bisplrep(xx, yy, zz, s=0) to interpolate the missing points between the values.

I want to describe the code but I dont know if I should say mathematical interpolation using a code or numerical interpolation?

Would someone please explain the difference

• I never met those expressions. Interpolation is unambiguous. What makes you think that there are two concepts ? – Yves Daoust Oct 19 '18 at 19:28
• @YvesDaoust, thank you for your reply. Because I am using a code rather than equation. So, I thought may be there is different way for expressing it. If I said a mathematical interpolation, I am not using an equation. Any suggestions how to describe it? – Rory Oct 19 '18 at 19:51
• "If I said a mathematical interpolation, I am not using an equation.": what ?? – Yves Daoust Oct 19 '18 at 19:52
• Sorry, I know it is a bit confusing, please bear with me. I am trying to write my report and explain what I did in my data set. Part of the data set was interpolated using a code not an equation. Python provides 'tck = interpolate.bisplrep(xx, yy, zz, s=0)' for interpolation the values. So, would you please tell me if it is okay to say mathematical interpolation to describe the code? – Rory Oct 19 '18 at 19:55
• It's ok to say interpolation. Mathematical interpolation won't be understood. – Yves Daoust Oct 19 '18 at 19:57
