How do i reflect over the y axis
WebOct 31, 2024 · You can use the function flip to flip any array along one axis: Aa = flip (A,2); This will work for both a gray-scale and an RGB image. This is equivalent to the following indexing expression for a 3D array (such as an RGB image): Aa = A (:,end:-1:1,:); WebJan 22, 2016 · To reflect over a vertical line, such as x = a, first translate so the line is shifted to the y-axis, then reflect over it, then translate back so the line is shifted to its original position. ( x, y) ↦ ( x − a, y) ↦ ( a − x, y) ↦ ( 2 a − x, y) In this case to reflex over x = − 1 we shift x ↦ x + 1, reflect ↦ − 1 − x and shift back ↦ − 2 − x

WebJun 30, 2011 · When you graph the 2 lines on the same axes, it looks like this: Note that if you reflect the blue graph (y = 3x + 2) in the x -axis, you get the green graph (y = −3x − 2) (as shown by the red arrows). What we've done is to take every y -value and turn them upside down (this is the effect of the minus out the front). Now for f (− x) WebYou can use a formula. When you reflect over x-axis the coordinates are (x,-y) and when you reflect over the y-axis the coordinates are (-x,y. If you want to reflect over y=x then the …
