L2 h1 p; E 9 w# h; l0 v$ @& D: e+ p! z$ Z) OIf 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.% ~( y# {3 S% }3 G

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。$ \ k" F1 I+ U5 R3 D* Y0 `
