Matlab元素划分为零(Matlab element-wise division by zero)

 我有两个矩阵，比如X = [1 2; 3 4; 5 6]和Y = [0 1; -1 1; 1 1]。 我想执行元素分割X./Y，但我需要一种方法来忽略Y中的所有零。 
 
 我尝试过使用类似的东西： 
 
 nonzeros = find（Y~ = 0）; X（非零）./ Y（非零）; 
 
 但这样做会导致结果成为列向量，我需要结果矩阵的形状与X（或Y）相同，并且需要零，其中Y为零。 所以我对这个案子的期望结果是[0 2; -3 4; 5 6]。 
 
 我也尝试了这里建议的内容（ 右阵列分区：忽略除零除 ），但再次执行此操作会强制结果为列向量。 
 
 谢谢 

I have two matrices, say X = [1 2; 3 4; 5 6] and Y = [0 1; -1 1; 1 1]. I want to perform element-wise division X./Y, but I need a way to ignore all the zeros in Y. 
 
I tried using something like:
 
nonzeros = find(Y ~= 0); X(nonzeros) ./ Y(nonzeros);
 
but doing so caused the result to be a column vector, and I need the shape of the result matrix to be the same as X (or Y) and with zeros where Y was zero. So my desired result for this case is [0 2; -3 4; 5 6].
 
I also tried what was suggested here (Right Array Division : Ignoring division by zeroes), but doing this again forces the result to be a column vector.
 
Thanks
