WebYou can find the maximum point using the m a x and f i n d commands in Matlab: y m a x = m a x ( y); x m a x = x ( f i n d ( y == y m a x)); The other points do not exist in your data, i.e. there is probably no point that hits exactly the 20% line or the 50% line. For these you would need to interpolate. Share Cite Follow WebMar 19, 2024 · I'm trying to get the coordinates from a graph when Y cross the X axis (Y=0) and I'm having trouble finding this solution.
