下面的代码是用原始经纬度、亩产量是用矩阵表示的。当原始数据不是矩形域时,可以采用Excel表的形式输入MATLAB里面进行运算。 代码语言:javascript 复制 x=[34.2,34,34,34,34;33,33.2,33,33,33;32,32.7,32.5,32.6,32;31.5,31,31,31,31;30,30,30,30,30];y=[121,122,123,124,125;121,122.1,123,124,...
griddata和griddatan是MATLAB中用于插值的两个函数。 griddata函数用于将散点数据插值到规则网格上。给定一组散点数据,griddata函数根据这些数据在规则网格上进行插值。你可以指定网格的大小和形状,并选择所需的插值方法(如线性插值、最近邻插值或多项式插值)。该函数返回插值计算所得的网格数据。 griddatan函数用于将散点...
This MATLAB function fits a hypersurface of the form v = f(x) to the sample points x with values v.
MATLAB Online에서 열기 Since griddatan is the n-d generalization of griddata, I assume that for 2-d scenarios, they should have identical behavior. This is true for most cases. For example: uv = [-6,-13;-3,-9;-9,-2;-12,7;25,-14;16,-24;3,15]; ...
