Fixed-Point Blocks
- Dave Dee
The Fixed-Point Blockset blocks are grouped into the following categories based on usage.
Math Blocks
Block Name | Description |
Output the absolute value of the input. | |
Generate a constant value. | |
Generate the dot product. | |
Multiply the input by a constant. | |
Multiply the input by a constant matrix. | |
Output the minimum or maximum input value. | |
Multiply or divide inputs. | |
Indicate the sign of the input. | |
Add or subtract inputs. | |
Negate the input. |
Conversion Blocks
Block Name | Description |
