MATLAB：从双阵列矢量分配给单元阵列

Question

我有三个阵列，所有具有相同的尺寸：

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

如何可以采取对应于其中b为真索引鑫的元素，并分配他们到相应的地方在XOUT？

>> 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. 

Answer 1

其分配给xout之前，您应该使用功能NUM2CELL右手边转换为一个单元阵列：

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