    Description

    Add-On Required: This feature requires the MATLAB Coder Support Package for PyTorch and LiteRT Models add-on.

    You can use LiteRTModel objects to execute the model or to generate code in MATLAB® or Simulink®.

    Creation

    Create a LiteRTModel object by using the loadLiteRTModel function.

    Properties

    expand all

    Model path, specified as a character vector.

    Function names, specified as a cell array of character vectors.

    Object Functions

    Open Live Script

    Suppose that you have a LiteRT model named siso.tflite that takes one input and returns one output. Create a LiteRTModel object.

    myModel = loadLiteRTModel("siso.tflite")
    Loading the model. This may take a few minutes.

    myModel = 
  LiteRTModel contained in siso.tflite:
