stepImpl

System output and state update equations

Syntax

[output1,output2,...] = stepImpl(obj,input1,input2,...)

Description

[output1,output2,...] = stepImpl(obj,input1,input2,...) specifies the algorithm to execute when you run the System object™. Running the object calculates the outputs and updates the object’s state values using the inputs, properties, and state update equations. You can also run an object using function-like syntax instead of the step method. For example, if you define an FFT object using txfourier = dsp.FFT, you can run it simply by using txfourier().

stepImpl is called when you run the System object.

Note

You must set Access = protected for this method.

Input Arguments

obj

System object handle

input1,input2,...

Inputs to the System object

Output Arguments

output

Output returned from the System object.

Examples

expand all

Use the stepImpl method to increment two numbers.

methods (Access = protected)
   function [y1,y2] = stepImpl(obj,x1,x2)
      y1 = x1 + 1;
      y2 = x2 + 1;
    end
end

Tips

The number of input arguments and output arguments must be greater than or equal to the numbers returned by the getNumInputsImpl and getNumOutputsImpl methods, respectively.

Do not call release within the stepImpl method.
