我正在尝试将组件逻辑和（＆amp;＆amp;）应用于两个不同数组的元素。第一个映射已经分配的缓冲区，而第二个缓冲区是从头创建的：
Map<Array<unsigned short, DEPTHMAP_HEIGHT, DEPTHMAP_WIDTH, RowMajor> > hypothesisMat(hypothesis);
Array<short int, DEPTHMAP_HEIGHT, DEPTHMAP_WIDTH, RowMajor> depthmapDiff;
正如http://eigen.tuxfamily.org/dox/classEigen_1_1ArrayBase.html#afce9cebae4c9cbb9883e73d515b5570f中所建议的那样，我应用逻辑和两个布尔数组，在前两个数组中应用了更大和更低的运算符：
Array<bool, DEPTHMAP_HEIGHT, DEPTHMAP_WIDTH, RowMajor> rm1;
rm1 = (hypothesisMat>0) && (depthmapDiff<m_dm);
编译给出了以下错误：
