xor

Find logical exclusive-OR

collapse all in page

Syntax

C = xor(A,B)

Description

C = xor(A,B) performs a logical exclusive-OR of inputs A and B and returns an array or a table containing elements set to either logical 1 (true) or logical 0 (false). An element of the output is set to logical 1 (true) if A or B, but not both, contains a nonzero element at that same location. Otherwise, the element is set to 0.

For bit-wise logical XOR operations, see bitxor.

Create a truth table for xor.

A = [true false]
A = 1×2 logical array

   1   0


B = [true; false]
B = 2×1 logical array

   1
   0


C = xor(A,B)
C = 2×2 logical array

   0   1
   1   0

Since R2023a

Create two tables and perform a logical exclusive-OR of them. The row names (if present in both) and variable names must be the same, but do not need to be in the same orders. Rows and variables of the output are in the same orders as the first input.

A = table([0;2],[0;4],VariableNames=["V1","V2"],RowNames=["R1","R2"])
A=2×2 table
          V1    V2
          __    __

    R1    0     0 
    R2    2     4 


B = table([4;2],[3;0],VariableNames=["V2","V1"],RowNames=["R2","R1"])
B=2×2 table
          V2    V1
          __    __

    R2    4     3 
    R1    2     0 


xor(A,B)
ans=2×2 table
           V1       V2  
          _____    _____

    R1    false    true 
    R2    false    false

Input Arguments

collapse all

Operands, specified as scalars, vectors, matrices, multidimensional arrays, tables, or timetables. Inputs A and B must either be the same size or have sizes that are compatible (for example, A is an M-by-N matrix and B is a scalar or 1-by-N row vector). For more information, see Compatible Array Sizes for Basic Operations.

Inputs that are tables or timetables must meet the following conditions: (since R2023a)

  • If an input is a table or timetable, then all its variables must have data types that support the operation.

  • If only one input is a table or timetable, then the other input must be a numeric or logical array.

  • If both inputs are tables or timetables, then:

    • Both inputs must have the same size, or one of them must be a one-row table.

    • Both inputs must have variables with the same names. However, the variables in each input can be in a different order.

    • If both inputs are tables and they both have row names, then their row names must be the same. However, the row names in each input can be in a different order.

    • If both inputs are timetables, then their row times must be the same. However, the row times in each input can be in a different order.

Data Types: single | double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64 | logical | char | table | timetable
