bitget — Read selected one-based bit positions from integer-valued input.
B = bitget(A,bit) returns the value of each selected one-based bit. A scalar input expands, while nonscalar inputs must have exactly matching sizes.
Syntax
B = bitget(A, bit)
B = bitget(A, bit, assumedtype)Inputs
| Name | Type | Required | Default | Description |
|---|---|---|---|---|
A | NumericArray | Yes | — | Integer-valued input. |
bit | NumericArray | Yes | — | One-based bit position. |
assumedtype | StringScalar | No | — | Integer class used to interpret double input A. |
Returns
| Name | Type | Description |
|---|---|---|
C | NumericArray | Bitwise numeric result. |
Errors
| Identifier | When | Message |
|---|---|---|
RunMat:bitwise:InvalidInput | Inputs are not finite integer-valued numeric, logical, or gatherable gpuArray values. | bitwise operation: invalid input |
RunMat:bitwise:SizeMismatch | Input shapes violate the operation's expansion rule: binary bitwise functions use compatible-size expansion, while bit positions/counts require scalar expansion or exactly matching nonscalar sizes. | bitwise operation: array sizes are not compatible |
How bitget works
- All eight native integer classes are supported and the result preserves the data class.
- Bit positions must be finite positive integers within the selected storage width.
- Only data input selects GPU output ownership; scalar or exact-size bit-position input is a control.
Using bitget with coding agents
Open a RunMat example with live inputs, then ask the agent to explain how bitget changes the result.
Run a small bitget example, explain the result, then change one input and compare the output.
