Функция interp2d в ошибке выполнения Python ⇐ Python

[Anonymous]

У меня есть следующие данные, которые в MATLAB легко интерполируются с помощью функции interp2. Однако в Python при использовании interp2d возникает следующая ошибка:

RuntimeWarning: No more knots can be added because the number of B-spline
coefficients already exceeds the number of data points m.
Probable causes: either s or m too small. (fp>s)
kx,ky=3,3 nx,ny=17,11 m=90 fp=0.000013 s=0.000000
warnings.warn(RuntimeWarning(_iermess2[ierm][0] + _mess))


Я пытался использовать Griddata, но и в этом ничего не получилось.
Буду очень признателен за любое решение этих проблем.
