MATLAB^® language syntax and functions for HDL code generation

HDL Coder supports various 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 Replace a Function with a Lookup Table from the Command Line.
