Use this tool to perform operations (addition, subtraction or product) on matrices. Available in Excel with the XLSTAT software.
This tool allows to compute the inverse or the transpose of a matrix as well as to perform operations between two matrices A and B.
In the case of two matrices, the user can choose to use the original matrix or transform it prior to the operation. Two options are available:
Use the transpose matrix
Use the inverse matrix
The following matrix operations are available :
Addition: matrices A and B must be of the same size (same number of rows and same number of columns).
Subtraction: matrices A and B must be of the same size (same number of rows and same number of columns).
Product: the number of rows in matrix B must be equal to the number of columns in matrix A.
