MATLAB中单元格数组的逻辑索引

Question

我想要做

myCellArray = myCcellArray{indices} 

其中indices只是0s和1s,元素数与行数相同myCellArray,但不起作用.我该怎么办？

Answer 1

您需要使用括号而不是花括号来进行索引.

>> arr = cell(2,2);
>> arr{1,1} = magic(4);
>> arr{1,2} = 'Hello';
>> arr{2,1} = 42;
>> arr{2,2} = pi;
>> arr

arr = 

    [4x4 double]    'Hello' 
    [        42]    [3.1416]

>> idx = logical(zeros(2,2));
>> idx(1,1) = true;
>> idx(2,2) = true;
>> arr(idx)

ans = 

    [4x4 double]
    [    3.1416]
