C++调用matlab引擎实现三维图的绘制

% 定义点(x,y,z)
x = randn(50,1);
xmax = max(x);
xmin = min(x);
y = randn(50,1);
ymax = max(y);
ymin = min(y);
z = exp(sin(x.^2)) + exp(cos(y.^2));
N = 500; % 每个维度的数据点数
% 网格化x,y二维空间
[X,Y] = meshgrid(linspace(xmin,xmax,N),linspace(ymin,ymax,N));
% 采用插值法扩展数据，可用方法有'linear'(default)|'nearest'|'natural'|'cubic'|'v4'|
Z = griddata(x,y,z,X,Y,'v4');
