在 MATLAB Online 中打开

linspace(first_x, last_x, 5)

if the "5 coordinate points" includes the first and the last point.

If the requirement is 5 points excluding the first and last point, then increase the 5 in linspace() to 7.

If the requirement is to have 5 equal intervals, use 6 in linspace()

Only the first 7 points can be extracted, and points cannot be extracted evenly at a certain distance. This method is still not advisable, and I would like to discuss with you what new methods are available. Thanks for your answer.
