endpointcart¶
[x2, y2, lineslope] = endpointcart(x1, y1, linelength, lineangle, dispout)
Description¶
Find an end point of the straight line segment from its starting point (x1,y1) and its angle on cartesian coordinate
Inputs¶
- x1
- x of start point (first point)
- y1
- y of start point (first point)
- linelength=1;
- Length of a line segment
- lineangle=0;
- Angle of a line segment from start point (first point) toward end point (last point) in (Degree)
- dispout=’no’;
- Define to display outputs or not (‘yes’: display, ‘no’: not display)
Outputs¶
- x2
- x of end point (last point)
- y2
- y of end point (last point)
- lineslope
- Slope of a line segment from start point (first point) toward end point (last point) in (Degree)lineslope=tan(deg2rad(lineangle))
Examples¶
x1=3;
y1=3;
linelength=5;
lineangle=45;
[x2,y2,lineslope]=endpointcart(x1,y1,linelength,lineangle,'yes');
x1=[0;0;0;0;0;0;0;0];
y1=[0;0;0;0;0;0;0;0];
linelength=5;
lineangle=[0;45;90;135;180;225;270;315];
[x2,y2,lineslope]=endpointcart(x1,y1,linelength,lineangle,'no');
