' O, k3 E0 t# L) s# n4 ]
B = fliplr(A) returns A with its columns flipped in the left-right direction (that is, about a vertical axis).
0 z/ v! p- q6 m
( M+ G( y2 |# b2 t5 a: pB = fliplr (a) 返回 A, 其列在左右方向 (即关于垂直轴) 反转。

4 O* i% @1 Q$ D( ]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。
