step

System object: dsp.MatFileWriter
Package: dsp

Write one frame of MAT file data

Syntax

step(H,X)

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.

step(H,X) writes one frame of data, X , to the variable stored in the MAT file. The variable is assumed to be N-dimensional and a MATLAB built-in data type. The data is written to the file by concatenating 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.
