MATLAB Language Support

MATLAB^® language syntax and functions for HLS code generation

The MATLAB functions and language syntax supported for High-Level Synthesis code generation are available on 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.
