![]() |
A The number of columns: k in A must match the number of elements in X and must be greater than zero. For example, k must be greater than zero. If the number of columns in A does not match the number of elements in Vector, the VI sets A x Vector to an empty array and returns an error. |
![]() |
Vector is the input vector. |
![]() |
A x Vector is the output vector containing the result of A multiplied by Vector. |
![]() |
error returns any error or warning condition from the VI. |
If A is an n-by-k matrix, and X is a vector with k elements, the multiplication of A and X, Y = AX, results in a vector Y with n elements. Let Y represent the output A x Vector. The VI obtains the elements of Y using the formula
where n is the number of rows in A, and k is the number of columns in A and the number of elements in X.
