This MATLAB function returns interpolated values of a function of two variables at specific query points using linear interpolation.

The interp family of functions includes interp1, interp2, interp3, and interpn. Each function is designed to interpolate data with a specific number of dimensions. interp2 and interp3 use grids in meshgrid …

Apr 12, 2023 · I cannot use interp2 as MATLAB tells me my grid arrays do not have an NDGRID structure, but I am still able to do a surface plot with no errors.

Apr 25, 2018 · I have a 310*400 matrix, that contain NAN values. I will like to interpolate the data to eliminate the NAN. After applying this code, I observed that the NAN is still retained. A sample of my …

Sep 20, 2019 · I'm finding that the behavior of interp2 and interp3 is counterintuitive, and I'd like to understand how properly to use them. Here's a simple example using interp2: XX_grid = …

Use griddedInterpolant to perform interpolation on a 1-D, 2-D, 3-D, or N-D gridded data set.

Oct 29, 2023 · Can anyone help me understand the interp2 function well? I need to reconstruct a video given optical flow vectors. I did it in the following way: while hasFrame(video) frameRGB = …

Nov 2, 2022 · Since interp2 requires meshgrid format, from my reading of documentation, i guess that interp2 might not be a suitable function to use. Is it correct? What is difference between griddata, …

Jun 5, 2020 · I need to do a 2D interpolation for a matrix data, but when I use the interp2, the function report error "input grid is not a valid meshgrid". I am really confused since the input grid is generated …

Use scatteredInterpolant to perform interpolation on a 2-D or 3-D data set of scattered data.
