I am working with matrices in Excel 2010 and happened upon a problem. Excel can perform matrix multiplication (e.g. A1:B2 times A3:B4) by the mmult function and yields the correct answer. However, there is a problem when attempting to raise a single matrix to a power - e.g. A^3 (...
Daily volatility is then determined in three stages as follows using EXCEL’s matrix multiplication function, MMULT (), and square root function, SQRT (): Stage 1:Matrix 1 = MMULT (Variance Covariance Matrix, W) Stage 2:Matrix 2 = MMULT (WT, Matrix 1) ...
The first property of matrix transposition (see Section 2.3.2) tells us that the transposition of a matrix product is equivalent to the product of the transposition of each matrix, with the order of multiplication reversed: (AB)T = BT AT. This means that the two following representations of...
The mathematical approach for this problem is to use MMULT for the matrix multiplication =MMULT(TRANSPOSE(compsPerProduct),productQuantity) Sadly the formula is unlikely to appeal to those without a STEM background. There is an alternative using 365 array formulas. ...
