Description

$ W$ b: E3 ~8 j/ Y1 C2 c& L8 IB = fliplr(A) returns A with its columns flipped in the left-right direction (that is, about a vertical axis).

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.

8 T, F' D8 f/ M+ f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。

The order of the first and third columns of A is switched in B, while the second column remains unchanged.
