how to find XLINE AND YLINE intersection

n=3;
m=4;
for i=1:n
    xline(i);
    for j=1:m
        yline(j);
    end
end

how to plot it on graph... like how to show these imtersection points on graph

[Adam Danz]

Use the plot command. You may have to include hold on too.

[Star Strider]

The intersections (in this example) are at all combinations of (i,j), in that order.

[Star Strider]

A specific plot call is not necessary (at least in R2020a), since the xline and yline calls will plot those themselves, although adding:

axis([0 4 0 5])

will make the lines and intersections more easily visible, since the extremes would otherwise end up being coincident with the plot axes limits.

[Adam Danz]

To plot the intersection point, you will need to use plot() or scatter() etc.

[Star Strider]

Perhaps, although not to plot the lines themselves.

can we do it using mapshow? bcaz i did and i got the intersection points as picture

[Star Strider]

I have no idea. I do not have the Mapping Toolbox, so I cannot respond to that.
