用matlab编写等边六边形网格结构

以下是一种可能的等边六边形网格结构的MATLAB代码：

% Set the number of rows and columns
num_rows = 10;
num_cols = 10;

% Set the size of the hexagons
hex_size = 1;

% Initialize the coordinates and faces matrices
coords = zeros(num_rows*num_cols,2);
faces = zeros(num_rows*num_cols*2,3);

% Loop through each row and column to create the coordinates and faces
for i = 1:num_rows
    for j = 1:num_cols
        
        % Calculate the x and y coordinates of the center of the hexagon
        x = (i-1)*sqrt(3)*hex_size + mod(j-1,2)*sqrt(3)/2*hex_size;
        y = (j-1)*3/2*hex_size;
        
        % Add the coordinates to the matrix
        coords((i-1)*num_cols+j,:) = [x,y];
        
        % Add the faces to the matrix
        if j < num_cols % Not at right edge
            faces((i-1)*num_cols*2+(j-1)*2+1,:) = [(i-1)*num_cols+j, (i-1)*num_cols+j+1, i*num_cols+j];
            faces((i-1)*num_cols*2+(j-1)*2+2,:) = [(i-1)*num_cols+j+1, i*num_cols+j+1, i*num_cols+j];
        end
        if i < num_rows % Not at bottom edge
            faces((i-1)*num_cols*2+(j-1)*2+num_cols*2+1,:) = [(i-1)*num_cols+j, i*num_cols+j+1, i*num_cols+j];
            faces((i-1)*num_cols*2+(j-1)*2+num_cols*2+2,:) = [(i-1)*num_cols+j, (i-1)*num_cols+j+1, i*num_cols+j+1];
        end
        
    end
end

% Plot the hexagon mesh
trisurf(faces, coords(:,1), coords(:,2), zeros(size(coords(:,1))));
axis equal;

该代码使用两个嵌套的循环来创建每个六角形的中心坐标。然后，使用这些坐标计算每个六角形的顶点，并将顶点坐标和面索引存储在两个矩阵中。最后，使用MATLAB的trisurf函数将网格绘制到三维空间中。
