Concatenate bits of fi
objects
Create a fixed-point vector.
a = fi([1,2,5,7],0,4,0); disp(bin(a))
0001 0010 0101 0111
Concatenate the bits of the elements of a
.
y = bitconcat(a)
y = 4695 DataTypeMode: Fixed-point: binary point scaling Signedness: Unsigned WordLength: 16 FractionLength: 0
disp(bin(y))
0001001001010111
The word length of the output, y
, equals the sum of the word lengths of each element of a
.
Create two fixed-point numbers.
a = fi(5,0,4,0); disp(bin(a))
0101
b = fi(10,0,4,0); disp(bin(b))
1010
Concatenate the bits of the two inputs.
y = bitconcat(a,b)
y = 90 DataTypeMode: Fixed-point: binary point scaling Signedness: Unsigned WordLength: 8 FractionLength: 0
disp(bin(y))
01011010
The output, y
, is unsigned with a word length equal to the sum of the word lengths of the two inputs, and a fraction length of 0.
When a
and b
are both vectors of the same size, bitconcat
performs element-wise concatenation of the two vectors and returns a vector.
Create two fixed-point vectors of the same size.
a = fi([1,2,5,7],0,4,0); disp(bin(a))
0001 0010 0101 0111
b = fi([7,4,3,1],0,4,0); disp(bin(b))
0111 0100 0011 0001
Concatenate the elements of a
and b
.
y = bitconcat(a,b)

disp(bin(y))
00010111 00100100 01010011 01110001
The output, y
, is a vector of the same length as the input vectors, and with a word length equal to the sum of the word lengths of the two input vectors.
When the inputs are both matrices of the same size, bitconcat
performs element-wise concatenation of the two matrices and returns a matrix of the same size.
Create two fixed-point matrices.
a = fi([1,2,5;7,4,5;3,1,12],0,4,0); disp(bin(a))

The output, y
, is a matrix with word length equal to the sum of the word lengths of a
and b
.
a
— Input arrayInput array, specified as a scalar, vector, matrix, or multidimensional
array of fixed-point fi
objects. bitconcat
accepts varargin
number
of inputs for concatenation.
Data Types: fixed-point fi
b
— Input arrayInput array, specified as a scalar, vector, matrix, or multidimensional
array of fixed-point fi
objects. If b
is
nonscalar, it must have the same dimension as the other inputs.
Data Types: fixed-point fi
y
— Output arrayOutput array, specified as a scalar, vector, matrix, or multidimensional
array of unsigned fixed-point fi
objects.
The output array has word length equal to the sum of the word lengths of the inputs and a fraction length of zero. The bit representation of the stored integer is in two's complement representation. Scaling does not affect the result type and value.
If the inputs are all scalar, then bitconcat
concatenates
the bits of the inputs and returns a scalar.
If the inputs are all arrays of the same size, then bitconcat
performs
element-wise concatenation of the bits and returns an array of the
same size.
For VHDL®, generates the concatenation operator: (a &
b)
.
For Verilog®, generates the concatenation operator: {a ,
b}
.
