This line of code calculates the number of steps needed to move from point p1 to point p3 with a certain step size.
Here's a breakdown of the code:
- `sqrt()` is a function that calculates the square root of a given value.
- `(p3(1)-p1(1))^2` calculates the difference of the x-coordinates of p3 and p1, and then raises it to the power of 2.
- `(p3(2)-p1(2))^2` calculates the difference of the y-coordinates of p3 and p1, and then raises it to the power of 2.
- `(p3(3)-p1(3))^2` calculates the difference of the z-coordinates of p3 and p1, and then raises it to the power of 2.
- These three calculations are multiplied together to get the total distance between p1 and p3.
- This distance value is then divided by the step size to get the number of steps needed to reach p3 from p1.
So in summary, this line of code calculates the number of steps needed to move from p1 to p3 with a certain step size.
