处理二维数组的运算，确保各值不重复。定位单元格的精确位置，通过行列的交集。MMULT函数：矩阵乘法的实现。MMULT函数用于计算矩阵乘积，尤其在Excel中使用时，其概念可能较为复杂。为助理解，插入图示展示MMULT函数的运作过程，直观呈现其强大功能。子程序mmult，创建于2023.03.25。--- --- 更新至4.2版...
当我们需要对矩阵进行乘法运算时，MMULT函数（MATRIX MULTIPLICATION）便派上用场。这个函数的作用在于计算矩阵之间的乘积，尽管在Excel中可能不那么直观，但通过几张示意图，我们可以更深入地理解它的强大功能。至于TRANSPOSE函数，它则是用于对数组进行转置操作，改变元素的行与列顺序，这对于调整矩阵运算的顺...

since theBarray is just the transpose of theAarray, there is no need to handle it explicitly. We can derive it from theAarray, somehwhat similar tohere, although that is performing AT x A the matrix multiplication of A x AT involves taking the dot-product of the rows of matrix...
The commutation matrix (or vec-permutation matrix) is used to transform thevectorization of a matrixinto the vectorization of its transpose and to commute the factors of a Kronecker product. Definition We start with a definition. DefinitionA ...
We'll see later that computation of a function of a tuple is conveniently implemented as a multiplication of the tuple by a matrix. Given the preceding discussion, it should be clear that we could represent tuples as row or column matrices, and simply use the matrix or its transpose, respe...
