find point of intersection between line and altitude


find point of intersection between line and altitude

hop of those help? I am trying to find the point of intersection between a line the altitude of a point to that line. So given the information, two points that create a line and one point to draw the altitude from, I want to find the point on the line that is closest to the point, (so a point on the line that forms a perpendicular line with the given point.)
code :
double x = (point.getY() - oppRec * point.getX() - line.getPoint1().getY() + slope * line.getPoint1().getX()) / (slope - oppRec);
double y = oppRec * x + point.getY() - oppRec * point.getX();

With these it helps I found a solution: it's here.
The idea is to make use of vector algebra, to use the dot and cross to simply the question until this stage:
code :
a (V1 X V2) = (P2 - P1) X V2

it helps some times How can I find the exact y-coordinate of the red gaussian at x = 0.5 without using Data Cursor? , Getting XData as well should give you the right x-values:
code :
C = get(get(gca, 'Children'), 'XData');
XPlotRange = [0.1 0.85];
XDataRange = [1 100];
XPlotToInterp = 0.5;
XDataToInterp = XDataRange(1) + (XPlotToInterp - XPlotRange(1))*diff(XDataRange)/diff(XDataRange);
XData1 = floor(XDataToInterp);
XData2 = ceil(XDataToInterp);
YInterp = interp1([XData1 XData2], [YData(XData1) YData(XData2)], XDataToInterp);

This might help you Hello I need to find Intersection point between 2 plots, one is curved and another is straight line as mentioned in the below figure , Try this
code :
import numpy as np
n = len(lst)
y = np.linspace(y1, y2, n)
close = np.argwhere(np.isclose(lst, y, rtol = 1/n)
print(close)
