Array-Vector Multiply
Multiplies the elements of a vector by the elements of an array along the specified dimension.
Description
Block Array-Vector Multiply multiplies the values of the n-dimensional input array A by the values in the input vector V in the given dimension.
The length of the input V must be the same as the length of the given dimension A. The block Array-Vector Multiply multiplies each element of V by the corresponding element of A.
Consider a three-dimensional input array A (i, j, k) of size M by N by P and an input vector V of size N by 1. If the parameter Multiply along dimension is set to 2, the output of the block Y(i,j,k):
,
where:
The output of the block Array-Vector Multiply has the same size as the input array A. This block supports valid and complex input data.
Ports
