uint32 — Convert values to unsigned 32-bit integer class.
uint32(X) converts numeric, logical, character, symbolic-constant, and real gpuArray inputs to unsigned 32-bit integer values using saturating rounded conversion.
Syntax
Y = uint32(X)Inputs
| Name | Type | Required | Default | Description |
|---|---|---|---|---|
X | Any | Yes | — | Input scalar/array value to convert. |
Returns
| Name | Type | Description |
|---|---|---|
Y | NumericArray | uint32-converted output value. |
Errors
| Identifier | When | Message |
|---|---|---|
RunMat:uint32:InvalidArgument | Optional arguments are malformed or unsupported. | uint32: invalid argument |
RunMat:uint32:InvalidInput | Input value cannot be converted to uint32. | uint32: invalid input |
RunMat:uint32:Internal | Internal conversion, gather, or provider upload failed. | uint32: internal error |
How uint32 works
- Rounds fractional numeric values to the nearest integer.
- Clamps negative values and
NaNto0. - Clamps values larger than
intmax('uint32')to4294967295. - Converts all eight integer classes directly from native storage without a floating-point intermediate.
- Preserves array shape. A complex host input remains complex when its converted imaginary component is zero.
- Real gpuArray inputs return provider-owned native uint32 storage; complex gpuArray conversion requires provider support for paired complex-integer storage.
Does RunMat run uint32 on the GPU?
The active provider performs real integer conversion through its native cast hook.
Paired-complex gpuArray conversion preserves exact components, class, owner, and residency through an owner-resolved fallback when a direct provider cast is unavailable.
GPU memory and residency
Real gpuArray inputs remain resident and return native uint32 storage owned by the same provider.
Example
Saturating scalar conversion
uint32([-1 3.5 4294967296])Expected output:
ans =
1x3 uint32 array
0 4 4294967295Using uint32 with coding agents
Open a RunMat example with live inputs, then ask the agent to explain how uint32 changes the result.
Run a small uint32 example, explain the result, then change one input and compare the output.
FAQ
Does uint32 preserve array shape?⌄
Yes. Non-scalar array inputs keep their original dimensions and are tagged with the uint32 numeric class.
