如何删除包含所有整数的矩阵行? [英] How do i remove matrix rows that contain all integers?

问题描述

假设我有一个7x3的矩阵，其中包含整数和非整数.我想要的是删除仅包含整数的所有行.示例如下:

Assuming I have a 7x3 matrix which contains both integers and non-integers. What i would want is to remove all rows containing only integers. An example is as follows:

A = [1, 1, 2
     2, 1.5, 1
     3, 1.5, 2
     1, 2, 1
     2, 2.5, 1
     3, 2.5, 1
     1, 3, 2];

我的输出应该是:

B = [2, 1.5, 1
     3, 1.5, 2
     2, 2.5, 1
     3, 2.5, 1];

请，我怎么可能做到这一点?谢谢.

Please, how can I possibly achieve this? Thank you.

推荐答案

B = A;
B(all(mod(A,1)==0, 2), :) = [];
