How do you find the intersection of two lines in Matlab?
- t=0:.1:10;
- y1=sin(t); % say f1.
- y2=exp(t); %f2.
- intersection=find(y1==y2);
How do you find the intercept of two lines?
- Get the two equations for the lines into slope-intercept form. …
- Set the two equations for y equal to each other.
- Solve for x. …
- Use this x-coordinate and substitute it into either of the original equations for the lines and solve for y.

How do you find the intercept in Matlab?
If you want to find X-intercept as interpolate between 2 closest points around X axes you can use INTERP1 function: x0 = interp1(y,x,0); It will work if x and y are monotonically increasing/decreasing.
How do you use Ginput in Matlab?
[ x , y ] = ginput( n ) allows you to identify the coordinates of n points within Cartesian, polar, or geographic axes. To choose a point, move your cursor to the desired location and press either a mouse button or a key on the keyboard. Press the Return key to stop before all n points are selected.
How do you find the intersection of two lines on a TI 84?
- Press [Y=] to display the Y= Editor.
- Press [X] [+] [1] [ENTER].
- Press [2] [X] [+] [4] [ENTER].
- Press [GRAPH] to display the graphs of the two functions.
- Press [2ND] [CALC] [5].
- When “First curve?” is displayed, press [▲] or [▼] if necessary to move the cursor to the first function.
How do you find the intersection of two perpendicular lines?
Substitute the y value into either of the original equations to find the x value: x + 0 = -3, and x = -3. So the point of intersection of the two lines is (-3,0). How do I find the line that passes through the point of intersection and a perpendicular line? Use the quadratic equation -b(square root) b^2-4ac / 2a.
How do I plot a function in Matlab?
- To plot a set of coordinates connected by line segments, specify X and Y as vectors of the same length.
- To plot multiple sets of coordinates on the same set of axes, specify at least one of X or Y as a matrix.

How do I use Gtext in Matlab?
gtext( str ) inserts the text, str , at the location you select with the mouse. When you hover over the figure window, the pointer becomes a crosshair. gtext is waiting for you to select a location. Move the pointer to the location you want and either click the figure or press any key, except Enter.
How do I find data points in Matlab?
- Make the figure containing the plot the current figure. …
- Call the gca command to get the current axes within that figure. …
- Get the coordinates from the XData and YData properties of the Line object.
What is Ginput Matlab?
Description. ginput enables you to select points from the figure using the mouse for cursor positioning. The figure must have focus before ginput receives input. [x,y] = ginput(n) enables you to select n points from the current axes and returns the x- and y-coordinates in the column vectors x and y , respectively.
What is intersect function?
intersect: Intersection of Subsets
Calculates the intersection of subsets of a probability space. Comparisons are made row-wise, so that in the data frame case, intersect(A,B) is a data frame with those rows that are both in A and in B .
What is the opposite of intersect in R?
outersect(): The opposite of R’s intersect() function
setdiff() produces all elements of the first input vector without any matching elements from the second input vector (i.e. is asymmetric).

How do you find the point of intersection of two functions?
When the graphs of y = f(x) and y = g(x) intersect , both graphs have exactly the same x and y values. So we can find the point or points of intersection by solving the equation f(x) = g(x). The solution of this equation will give us the x value(s) of the point(s) of intersection.
How do you find the points on a TI 84 Plus CE?
- Press [Trace]. Then use the right and left arrow keys to move along the curve. …
- Use the Up or Down arrow keys to switch functions. Then use the Right and Left arrow keys to trace.
- Alternatively, [2nd] [CALC] provides a menu of items. Choose “5: intersect”.
