In this code, we plot the video and eye position separately to adjust the y-axis limits of both plots to match the reversed y-axis of the eye position data. Then we plot them together using imshow for the video and plot for the eye position, with the hold on and hold off commands to combine the plots. We also adjust the y-coordinates of the eye ... Description. B = flip(A) returns array B the same size as A , but with the order of the elements reversed. The dimension that is reordered in B depends on the shape of A: If A is vector, then flip(A) reverses the order of the elements along the length of the vector. If A is a matrix, then flip(A) reverses the elements in each column.

However the Y axis nees to go from ~6 in the bottom left to ~19 in the top left - the axis in this image are reversed. What am I doing wrong with my code? I've tried using ydata straight, flipping it, etc but that hasn't worked. Whenever I set YDir it always flips the image so that the red in at the bottom, but then the axis looks ok.

Only setting the 'YDir' property of the axes to 'normal' will flip how the y-axis is displayed, causing the image to appear upside down. To account for this, we use the "flipud" function to flip the image back. Essentially, we are flipping it horizontally twice, so the end result should not appear flipped.ytickangle(angle) rotates the y -axis tick labels for the current axes to the specified angle in degrees, where 0 is horizontal. Specify a positive value for counterclockwise rotation or a negative value for clockwise rotation. example. ytickangle(ax,angle) rotates the tick labels for the axes specified by ax instead of the current axes.In this modern era of smartphones and touchscreens, flip phones may seem like a thing of the past.

The user has the option of excluding. Description. B = flipud(A) returns A with its rows flipped in the up-down direction (that is, about a horizontal axis). If A is a column vector, then flipud(A) returns a vector of the same length with the order of its elements reversed. If A is a row vector, then flipud(A) simply returns A. For multidimensional arrays, flipud operates on the ...

You can change the direction of increasing values along the y-axis by setting the YDir property of the Axes object. If you want the values to increase from bottom to top (2-D view), then set the value to 'normal'. Alternatively, if you want the values to decrease from bottom to top, then set the value to 'reverse'. To reverse the order of its columns, I type the fliplr (M) command. M2=fliplr (M) M2 will be a new matrix obtained by flipping M1 horizontally about the y-axis, with the columns reversed." M 2 = (2 1 4 3) M 2 = ( 2 1 4 3) To reverse the order of rows in a matrix M, I can use the built-in flipud (M) function, which flips the matrix vertically.
