fi Best Practices Review

Reviews MATLAB code for fixed-point (fi) best practices and suggests improvements for performance, code generation efficiency, and correctness.

When to Use

• Reviewing MATLAB code that uses fi, fimath, numerictype, or quantizenumeric
• Optimizing fixed-point simulation speed
• Preparing fixed-point code for C or hardware code generation

When Not to Use

• Code using only built-in integer types (int8, uint16, etc.) without fi
• Pure floating-point algorithms with no fixed-point intent
• Simulink-only workflows where fixed-point is configured through block dialogs (use Fixed-Point Tool instead)

Checklist

When reviewing code, check for ALL of the following:
