Syntax

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.

Q = step(H,I) returns the quantized output values Q corresponding to the input indices I. The data type of I can be uint8, uint16, uint32, int8, int16, or int32. The OutputDataType property determines the data type of Q.

Q = step(H,I,C) uses input C as the codebook values when the CodebookSource property is Input port. The data type of C can be double, single, or fixed-point. The output Q has the same data type as the codebook input C.

Note:   H 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.
