The discussion revolves around the challenge of drawing a quadrilateral in MATLAB using line equations rather than coordinates. Participants explore methods to plot the polygon defined by the equations of its sides while addressing concerns about line extensions and intersections.
Participants express differing views on the complexity of finding intersections between lines and whether to use coordinates. There is no consensus on the best approach to draw the quadrilateral.
Participants mention the need to solve equations to find vertices, but there is no agreement on the method or ease of doing so. The discussion includes assumptions about the constants involved and the definitions of the axes.
plot or fplot functions to plot the lines. Remember to use hold on between drawing the graphs.Are you saying that you don't want the sides be extended? In that case, you'll have to solve two equations at a time and find the coordinates of the four vertices. Then draw the lines from one vertex to the other, i.e. range ##x## from one vertex to the other, find ##y## for intermediate points, and plot.If you give the four equations, I can help you start.minhduc515 said:
Two small questions: 1. One axis is X, the other is y or R? 2. Is everything other than x and you a constant (including z)?minhduc515 said:
Finding the intersection between two lines is just a matter of solving a trivial linear system ...minhduc515 said:
