如何在不进行MATLAB排序的情况下从A中删除集合A和B的交集? [英] How do I delete the intersection of sets A and B from A without sorting in MATLAB?

问题描述

两个矩阵A和B:

A = [1 2 3
     9 7 5
     4 9 4
     1 4 7]

B = [1 2 3
     1 4 7]

矩阵B的所有行都是矩阵A的成员.我希望不进行排序就从A删除A和B的公共行.

All rows of matrix B are members of matrix A. I wish to delete the common rows of A and B from A without sorting.

我尝试过setdiff()，但这对输出进行了排序.

I have tried setdiff() but this sorts the output.

对于我的特殊问题(蛋白质结构中的原子坐标)，保持行的有序完整性很重要.

For my particular problem (atomic coordinates in protein structures) maintaining the ordered integrity of the rows is important.
