写出matlab中距离变化使用函数代码

Sure, here's an example code for the distance function in MATLAB:

% Create two arrays representing two points in 3D space
point1 = [3, 5, 2];
point2 = [-1, 2, 6];

% Calculate the Euclidean distance between the points
distance = norm(point1 - point2);

The `norm` function calculates the Euclidean distance between two points, which is simply the length of the line connecting the points in 3D space. This code should work for any two points in 3D space.
