Convert Fixed-Point Conversion Project to MATLAB Scripts

You can convert an existing Fixed-Point Converter app project to a MATLAB^® script. You can use the -tocode option of the fixedPointConverter command to create a script for fixed-point conversion. You can use the script to repeat the project workflow in a command-line workflow. Before you convert the project to a script, you must complete the Test step of the fixed-point conversion process.

Generate Scripts

1. Change to the folder that contains the project file.

2. Use the -tocode option of the fixedPointConverter command to convert the project to a script. Use the -script option to specify the file name for the script.

   fixedPointConverter -tocode conversion_project.prj -script conversion_project_script.m

   The fixedPointConverter command generates a script in the current folder. conversion_project_script.m contains the MATLAB commands to:

   • Create a floating-point to fixed-point conversion configuration object that has the same fixed-point conversion settings as the project.

   • Run the fiaccel command to convert the MATLAB function conversion_project to the fixed-point MATLAB function conversion_project_fixpt.

   The fiaccel command overwrites existing files that have the same name as the generated script. If you omit the -script option, the fiaccel command returns the script in the Command Window.

Run Script That Generates Fixed-Point MATLAB Code

If you want to regenerate the fixed-point function, use the generated script.

1. Make sure that the current folder contains the entry-point function conversion_project.m and the associated test bench file conversion_project_test.m.

2. Run the script.

    conversion_project_script

   The script generates conversion_project_fixpt.m in the folder codegen\conversion_project\fixpt. The variables cfg and ARGS appear in the base workspace.
