help 一下帮助,你会发现:
X,Y — Sample grid pointsmatrices | vectors
Sample grid points, specified as real matrices or vectors.
If X and Y are
matrices, then they contain the coordinates of a full grid (in meshgrid format).
Use the meshgrid function to
create the X and Y matrices
together. Both matrices must be the same size.If X and Y are
vectors, then they are treated as a grid vectors. The values in both vectors
must be strictly
monotonic and increasing.
也就是说 要求你的x,y严格单调,所以你的x是不符合要求的,因此报错追问那就只能进行两次插值来找某一个点了？追答不是一一对应的函数关系插值意义不大 检查你的X,Y数据看是否真的必须这样?
