I want to filter out the line when it intersects with another line.
I only need the line before instecting with another line.
I found the function that calculate intersection point. but in my case i don't need a point. I just need to filter out the line after intersection.
Thanks.

You can use intersectionHull from this FEX download,
Use the upward sloping line to define inequality constraints for the desired region.

For example,
V1=[-1 +1;
+2 -2]; %downsloping line
V2=[-1 -1;
+1 +1]; %upsloping line
[~,~,A,b]=vert2lcon(V2)
V3=intersectionHull('vert',V1,'lcon',A,b).vert;
close all
lfn=@(v,varargin) line(v(:,1),v(:,2),varargin{:});
lfn(V1)
lfn(V2)
lfn(V3,Color='r',Marker='o')
