# Copyright 2024-2025 The MathWorks, Inc.
# This Dockerfile allows you to build a Docker® image with MATLAB® installed using the MATLAB Package
# Manager and licensed using MATLAB Batch Licensing. Use the optional build arguments to customize the
# version of MATLAB, list of products to install, and the location at which to install MATLAB.

# Here is an example docker build command with the optional build arguments.
# docker build --build-arg MATLAB_RELEASE=R2025b
#              --build-arg MATLAB_PRODUCT_LIST="MATLAB Deep_Learning_Toolbox Symbolic_Math_Toolbox"
#              --build-arg MATLAB_INSTALL_LOCATION="/opt/matlab/R2025b"
#              -t my_matlab_image_name .

# To specify which MATLAB release to install in the container, edit the value of the MATLAB_RELEASE argument.
# Use uppercase to specify the release, for example: ARG MATLAB_RELEASE=R2021b
ARG MATLAB_RELEASE=R2025b

# Specify the list of products to install into MATLAB.
ARG MATLAB_PRODUCT_LIST="MATLAB"

# Specify MATLAB Install Location.
ARG MATLAB_INSTALL_LOCATION="/opt/matlab/${MATLAB_RELEASE}"

# When you start the build stage, this Dockerfile by default uses the Ubuntu-based matlab-deps image.
# To check the available matlab-deps images, see: https://hub.docker.com/r/mathworks/matlab-deps
FROM mathworks/matlab-deps:${MATLAB_RELEASE}

# Declare build arguments to use at the current build stage.

ARG MATLAB_PRODUCT_LIST
