bitxor

Bitwise XOR of two fi objects

collapse all in page

Syntax

c = bitxor(a,b)

Description

c = bitxor(a,b) returns the bitwise exclusive OR of fi objects a and b in fi object c.

The output is determined as follows:

  • Elements in the output array c are assigned a value of 1 when exactly one of the corresponding bits in the input arrays has a value of 1.

  • Elements in the output array c are assigned a value of 0 when the corresponding bits in the input arrays have the same value (e.g. both 1's or both 0's).

Note

This function only supports fi objects with fixed-point data types. To compute bitwise XOR of other data types, use the bitxor function.

Find the bitwise exclusive OR of fi objects a and b.

a = fi(-28,1,6,0);
b = fi(12, 1, 6, 0);
c = bitxor(a,b)
c = 
   -24

          DataTypeMode: Fixed-point: binary point scaling
            Signedness: Signed
            WordLength: 6
        FractionLength: 0

To verify the result, examine the binary representations of a, b, and c.

binary_a = a.bin
binary_a = 
'100100'

binary_b = b.bin
binary_b = 
'001100'

binary_c = c.bin
binary_c = 
'101000'

Input Arguments

collapse all

Input fixed-point fi objects, specified as scalars, vectors, matrices, or multidimensional arrays. a and b must have the same dimensions unless one is a scalar.

The numerictype properties associated with a and b must be identical. If both inputs have an attached fimath object, their local fimath properties must be identical. If the numerictype is signed, then the bit representation of the stored integer is in Two's Complement representation.

Data Types: fi
Complex Number Support: Yes
