bitxorreduce

Reduce consecutive slice of bits to one bit by performing bitwise exclusive OR operation

Syntax

c = bitxorreduce(a)
c = bitxorreduce(a, lidx)
c = bitxorreduce(a, lidx, ridx)

Description

example

c = bitxorreduce(a) performs a bitwise exclusive OR operation on the entire set of bits in the fixed-point input, a. It returns the result as an unsigned integer of word length 1.

example

c = bitxorreduce(a, lidx) performs a bitwise exclusive OR operation on a consecutive range of bits. This operation starts at position lidx and ends at the LSB (the bit at position 1).

example

c = bitxorreduce(a, lidx, ridx) performs a bitwise exclusive OR operation on a consecutive range of bits, starting at position lidx and ending at position ridx.

The bitxorreduce arguments must satisfy the following condition:

a.WordLength >= lidx >= ridx >= 1

Input Arguments

collapse all

Input array, specified as a scalar, vector, matrix, or multidimensional array of fixed-point fi objects.

bitxorreduce supports both signed and unsigned inputs with arbitrary scaling. The sign and scaling properties do not affect the result type and value. bitxorreduce performs the operation on a two's complement bit representation of the stored integer.

Data Types: fixed-point fi

Start position of range specified as a scalar of built-in type. lidx represents the position in the range closest to the MSB.

Data Types: fi | single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64

End position of range specified as a scalar of built-in type. ridx represents the position in the range closest to the LSB (the bit at position 1).

Data Types: fi|single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64

Output Arguments

collapse all

Output array, specified as a scalar, vector, matrix, or multidimensional array of fixed-point fi objects. c is unsigned with word length 1.
