## Description

Converts a double-precision Simulink system or subsystem to single precision using DataTypeWorkflow.Single (Fixed-Point Designer). The single conversion replaces all user-specified double-precision data types, as well as output data types that compile to double precision, with single-precision data types. Use this skill when converting Simulink systems to single precision, reducing memory usage of a Simulink system, optimizing for embedded targets. Do NOT use for standalone MATLAB .m code single conversion.

# Single-Precision Conversion for Simulink Models (Fixed-Point Designer)

Toolbox: **Fixed-Point Designer**
Function: `DataTypeWorkflow.Single.convertToSingle`

Converts user-specified double-precision data types, across block settings, Stateflow chart
settings, signal objects, and bus objects, to single precision. **Boolean, built-in integer
(int8, uint8, int16, …), and fixed-point types are left unchanged.**

## When to Use

- Converting a Simulink model (`.slx`) or subsystem from double-precision to single-precision
- Reducing memory footprint for embedded hardware with native single-precision support
- Batch/CI conversions, checking conversion compatibility, or verifying no stowaway doubles remain
- Summarizing the single conversion compatibility report and conversion result for the user in plain language

## When NOT to Use

- **Standalone MATLAB `.m` code**, use the `convertToSingle` function with `coder.config('single')` instead
- **Fixed-point data type optimization**, use `DataTypeWorkflow.Converter` instead
- **Approximating a function or shrinking Lookup Table blocks with LUTs**, use `simulink-optimize-lookup-tables` instead

---

## Public API

```matlab
ConversionReport = DataTypeWorkflow.Single.convertToSingle(systemToConvert)
```

- `systemToConvert` (char), full block path of the **loaded** model or subsystem (e.g. `'myModel'` or `'myModel/Controller'`).
- `ConversionReport` (struct), compatibility check, converted items, and verification status (see field tables below).

Worked example: `openExample("fixedpoint/ConvertSystemToSinglePrecisionExample")`
