Compute intersection between lines

Le't say I have 2 matrices that represent lines

Let's say you have A a 16x2 matrix that represents one set of lines shown below

And then there is B a 12x2 matrix representing another set of lines shown below

I know interx can be used to find intersection between lines,curves etc. but what i want to do is take the first line of A and find its intersection with the last line of B

similarly second line of A intersects with second last line of B

As of now this is what i came up with

for i=1:2:size(L_seg_proj,1)
    
    L1=L_seg_proj(i:i+1,:);
    for j=1:2:size(R_seg_proj,1)
        L2=R_seg_proj(j:j+1,:);
        P=InterX(L1,L2);   
    end
    
end

But the issue with this is that for every line in L_seg_proj(L1) it computes intersection between L1 and all the lines in R_seg_proj.

Any ideas on what I can do to rectify this?
