Note the last two are identical and that all it takes is using both an x,y vector in plot.

Since barh wants the bin centres, one way to calculate them is to take the mean of the difference of the regularly-spaced edges, divide it by 2, and added it to all but the highest bin edge. Example: Theme. Copy. edges = 1:5; centres = mean (diff (edges))/2 + edges (1:end-1); Label the x -axis and return the text object used as the label. plot((1:10).^2) t = xlabel( 'Population' ); Use t to set text properties of the label after it has been created. For example, set the color of the label to red. Use dot notation to set properties. t.Color = 'red'; Description. example. 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 ...The slight downside is that you must pass in the object to any and all axis modification commands that you want to make, even when the axis you are working on is current. Example: Theme. Copy. perm= [1,3,2]; %permute the y and z axes. ax=permAxis3D ( axes ,perm); %construct the object. hold on. grid on.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.2. In addition to Luis 's answer you can set the current axes View property to [90 -90] directly from the property inspector. Programmatically this is equivalent to this: set(gca,'View',[90 -90]) Note: Thanks to Luis for the correction. Using [-90 90] does swap the axis but then you need to reverse the direction of the y-axis.

For example, you can rotate a vector in any direction using a sequence of three rotations: v ′ = A v = R z ( γ) R y ( β) R x ( α) v. The rotation matrices that rotate a vector around the x, y, and z-axes are given by: …Description. example. B = rot90(A) rotates array A counterclockwise by 90 degrees. For multidimensional arrays, rot90 rotates in the plane formed by the first and second dimensions. example. B = rot90(A,k) rotates array A counterclockwise by k*90 degrees, where k is an integer.
