使用 scatteredInterpolant 对散点数据的二维或三维数据集执行插值。scatteredInterpolant 返回给定数据集的插值 F。您可以计算一组查询点（例如二维 (xq,yq)）处的 F 值，以得出插入的值 vq = F(xq,yq)。 Unsure why heatmaps cannot be produced. Linear and spline interpolation which is better to handle spectral data interpolation? Then you can get the whole field interpolated with the function griddata in matlab. Use F.Points = P to initialize F with the points in matrix P . Interpolating Scattered Data - MATLAB & Simulink - MathWorks The support engineers are great, they really know how to choose a good subject line that will get a developer's attention and get a response back to the customer quickly. Create a 10-by-10-by-10 grid of sample points. This computes an interpolating function for the observed points, allowing you to query the function anywhere within its convex hull. Interpolate 2-D or 3-D scattered data - MATLAB - MathWorks (2) You will now go around falsely believing that griddedInterpolant works poorly, just because you had an easier time getting scatteredInterpolant to work. scatteredInterpolant returns the interpolant F for the given data set. To fix this on a code level, you could switch to interpreted MATLAB code. F = scatteredInterpolant () creates an empty scattered data interpolant. Use F.Values = v to initialize F with the values in v. Input Arguments Properties Definitions Interpolant Interpolating function that you can evaluate at query locations. Because the answer is not how to modify the plot AFTER you used scatteredInterpolant, but how to use the tool properly (or the proper tool) to produce a better result. This produces a surface of the form V = F (X). Statistically how do I compare the performance of either spline or linear interpolation on the spectral data? This example shows how to extrapolate a well sampled 3-D gridded dataset using scatteredInterpolant. It is a quick and simple fix, but I recommend . Then you can get the whole field interpolated with the function griddata in matlab. . So yes this is possible and there are the necessary functions at least in matlab and I would guess that in other languages too. use scatteredInterpolant variable in embedded matlab function in ... How to interpolate scattered data to a regular grid in Python? Recently Added - in.mathworks.com So yes this is possible and there are the necessary functions at least in matlab and I would guess that in other languages too.
