MATLAB Language Support

MATLAB^® language syntax and functions for HDL code generation

The MATLAB functions and language syntax supported for HDL code generation are available from this page. If your MATLAB algorithm uses an unsupported function, you can generate code by replacing the function with a lookup table approximation. See Replacing Functions Using Lookup Table Approximations.
