step

System object: dsp.MatFileReader
Package: dsp

Read data from a variable in the MAT file

Syntax

X = step(H)

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) and y = obj() perform equivalent operations.

X = step(H) reads data, X, from a variable stored in a MAT-file. The variable is assumed to be N-dimensional and a MATLAB built-in datatype. The data is read into MATLAB by reading along the first dimension.

    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.
