Performs signum function (sign extraction) on the input.
Math Functions/Math Operations
The Signum block returns the sign for each element of the real input. The block returns 1, 0, or -1 if the number is positive, equal to 0, or negative, respectively.
When the input s is complex, the block output is calculated as:
sign(s) = s./ abs(s)
Where sign is the
signum function, and
indicates element-wise division.
Data Type Support
The Signum block supports signals of integer type, floating-point type (double, single and half), and fixed-point type for real inputs. The complex inputs are supported only for floating point data types.
The output data type, and dimension are the same as those of the input.
The Signum block has no parameters to set.
