How can I find if a line and a circle intersect.

I have and obstacle in the form of a circle and I am making a line in the form of a path. I would like to know if the is a way to check wether those two intersect or not. I have seen a line of code P=InterX(L1,L2) where L1,L2 are the equations of the circle and the line respectively. Is there any other way?

If you have the matrix data with you then you can try to find common numbers between those two matrices.

intersect(A,B);

This gives the code to find common numbers between 2 matrices

That would require to generate every poiont on the circle and the line right?

No. If you dont have the equation and you have the points on circle and line then it will the give the intersecting points but this is a bad way to do it. the better way would be to make a formula and use it .

Ok thank you very much!
