Statistica Visual Basic Library of Matrix Functions - MatrixInverse (Matrix, MatrixResult)
Parameter | Description |
Matrix | name of symmetric, non-singular, source data matrix (see Arrays in functions) |
MatrixResult | destination matrix (see Arrays in functions; may be the same as source Matrix, if desired) |
The MatrixInverse function will compute the inverse of the specified symmetric, non-singular, source Matrix (see also Arrays in functions) and place the result in the specified MatrixResult. The inverse of a matrix A is usually denoted as A-1 (matrix A to the power of minus 1). It is the matrix equivalent of the same operation performed on numbers. Specifically, for numbers, a*a-1=a/a=1; in matrix form: A*A-1=I, where I stands for the identity matrix (see MatrixIdentity).
