Examples

Load LiteRT Model

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 model...
Model loaded.

myModel = 
  LiteRTModel contained in siso.tflite:

Load LiteRT Model Using MEX Execution Mode

Suppose that you have a LiteRT model named mimo.tflite that takes multiple inputs and returns multiple outputs.

Create a LiteRTModel object by using the MEX execution mode. To use the MEX execution mode, you must install a supported C compiler. For more information about setting up the C/C++ compiler, see Installing and Configuring Prerequisite Products.

myModel = loadLiteRTModel("mimo.tflite",ExecutionMode="MEX")

Loading model...
Model loaded.

myModel = 
  LiteRTModel contained in mimo.tflite:

Input Arguments

modelFileName — Name of LiteRT model file

character vector | scalar string

Name of the LiteRT model file, specified as a character vector or a scalar string.

Example: "myModelName"

Example: "myfolder/myModelName"

ExecutionMode — Execution Mode

"JIT" (default) | "MEX"

Execution mode to use for MATLAB simulation behavior, specified as "JIT" or "MEX".

JIT code is incompatible with the OpenMP application interface. JIT execution mode does not support multi-threading. If you want to parallelize for-loops, use MEX execution mode. You must install a supported C compiler to use the MEX execution mode. For more information about setting up the C/C++ compiler, see Installing and Configuring Prerequisite Products.

Output Arguments

model — LiteRT model

LiteRTModel object

LiteRT model, returned as a LiteRTModel object.
