MATLAB:如果一个数组的一部分的任何一行含有一个数值
原标题:MATLAB: If any row of a part of an array contains a value

有没有办法缩短下面2号代码的线?

for i = 1:length(dataStructure)
    if dataStructure(1,i) == 100000000 || dataStructure(2,i) == 100000000 % this line
        dataStructure(:,i) = NaN;
    end
end

我本以为以下各点就足够了(但这行不通):

if dataStructure(:,i) == 100000000

换句话说, 我如何检查一个数组的一列中是否存在数字? 这里的问题是, 我无法预测数据结构是否有一行或两行, 因此无法使用嵌套环绕, 因为每次数据结构只有一行就会造成错误 。

最佳回答

您不需要循环 :

dataStructure(:,any(dataStructure==1e8,1) = NaN;

这叫逻辑索引,更多信息:这里
