step

System object: dsp.ArrayVectorMultiplier
Namespace: dsp

Multiply array by vector

Syntax

Y = step(avm,A,V)
Y = step(avm,A)

Description

Note

Starting in R2016b, instead of using the step method to perform the operation defined by the System object™, you can call the object with arguments, as if it were a function. For example, y = step(obj,x) and y = obj(x) perform equivalent operations.

Y = step(avm,A,V) returns Y , the result of multiplying the input array A by the elements of input vector V along the specified dimension when the VectorSource property is Input port. The length of the input V must equal the length of the specified dimension of A.

Y = step(avm,A) returns Y , the result of multiplying the input array A by the elements of vector specified in Vector property along the specified dimension when the VectorSource property is set to Property. The length of the vector specified in Vector property must equal the length of the specified dimension of A.

Note

obj specifies the System object on which to run this step method.

The object performs an initialization the first time the step method is executed. This initialization locks nontunable properties and input specifications, such as dimensions, complexity, and data type of the input data. If you change a nontunable property or an input specification, the System object issues an error. To change nontunable properties or inputs, you must first call the release method to unlock the object.
