Fixed-Point Toolbox™

Using the Embedded MATLAB Subset

There are several ways to use Fixed-Point Toolbox software with the Embedded MATLAB subset:

• The Embedded MATLAB emlmex function converts your M-code to a C-MEX function and can greatly accelerate the execution speed of your fixed-point algorithms in MATLAB. To use the emlmex function, you need a Fixed-Point Toolbox license. For more information, see Working with Embedded MATLAB MEX in the Embedded MATLAB documentation.

• The Embedded MATLAB Coder (emlc) is a Real-Time Workshop function that automatically converts M-code to C code. Using the Embedded MATLAB Coder allows you to accelerate your MATLAB code that uses Fixed-Point Toolbox software. To use the emlc function with Fixed-Point Toolbox software, you also need to have licenses for Simulink and Real-Time Workshop code generation software. For more information, see Working with Embedded MATLAB Coder in the Real-Time Workshop documentation.

• The Embedded MATLAB Function block allows you to use MATLAB code in your Simulink models that generate embeddable C code. To use the Embedded MATLAB Function block with Fixed-Point Toolbox software, you also need a Simulink license. For more information on the Embedded MATLAB Function block, see Using the Embedded MATLAB Function Block in the Simulink documentation.
