/ |  ^1 }/ v& i/ i0 i$ E# M
B = fliplr(A) returns A with its columns flipped in the left-right direction (that is, about a vertical axis).

; b, V' b6 ]( n5 E' bB = 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.

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。

结果 B 与 A 的大小相同, 但元素的水平顺序被翻转。操作会单独翻转每个页面上的元素。
