Syntax

Description
& ?6 f7 k3 e3 f1 h; Q, m
B = fliplr(A) returns A with its columns flipped in the left-right direction (that is, about a vertical axis).
+ g  U8 P( x" U. Z9 e! X
B = fliplr (a) 返回 A, 其列在左右方向 (即关于垂直轴) 反转。

If A is a row vector, then fliplr(A) returns a vector of the same length with the order of its elements reversed. If A is a column vector, then fliplr(A)simply returns A. For multidimensional arrays, fliplr operates on the planes formed by the first and second dimensions.

- P" U9 t9 l% K( T3 b0 j2 a, p如果 a 是行向量, 则 fliplr (a) 返回与其元素的顺序反转的相同长度的向量。如果 a 是列向量, 则 fliplr (a) 只是返回 a。对于多维数组, fliplr 在由第一个和第二个维度形成的平面上运行。
