Considering the many applications of mathematical functions in different ways, it is essential to have a defining function. In this study, we used Fuzzy Lagrangian interpolation and natural fuzzy spline polynomials to interpolate the fuzzy data.
In the current world and in the field of science and technology, interpolation issues are also of a fuzzy type, it has many scientific applications in developmental work, medical issues, imaging, engineering software and graphics. Therefore, in this article we intend to investigate Interpolation of fuzzy data in order to apply fuzzy interpolation, by optimizing fuzzy polynomials, also achieve the best approximation of a fuzzy function.
