我有三个数组,大小都一样:

xout        % cell array
xin         % numeric array of doubles
b           % logical array

如何获取与 b 为真的索引相对应的 xin 元素,并将它们分配给 xout 中的相应位置?

>> xout = {'foo', 'bar', 'baz', 'quux'};
>> xin = [1, 2, 3, 4];
>> b = (xin ~= 2);       % yields [1 0 1 1] in this case
>> xout{b}=xin(b);
??? The right hand side of this assignment has too few values 
to satisfy the left hand side.

>> xout(b)=xin(b);
??? Conversion to cell from double is not possible.

您应该使用该函数num2cell将右侧转换为元胞数组,然后再将其分配给xout

xout(b) = num2cell(xin(b));
