Description
The Binary Vector Conversion block encodes, decodes, and manipulates binary coded vectors. You can convert a scalar input to a logical (Boolean) vector signal using binary magnitude or two's complement and vice versa. You can also resize and reverse the bit index arrangement of the binary logic vectors.
Ports
Input
Input signal, specified as a scalar or logical vector.
When encoding, the input signal is a scalar.
When decoding, the input signal is a logical (Boolean) vector.
Note
When converting to a scalar value from a bit stream, any input greater than 1 is considered as logical '1'. Similarly any input bit is less than 0 is considered logical '0'.
Data Types: single
| double
| uint8
| uint16
| uint32
| Boolean
| fixdt(0,16)
Output
Output signal, specified as a scalar or logical vector.
When encoding, the output signal is a logical (Boolean) vector.
When decoding, the output signal is a scalar.
Data Types: single
| double
| uint8
| uint16
| uint32
| Boolean
| fixdt(0,16)
Parameters
Type of conversion, specified as one of these:
Scalar to binary-coded vector
— Encode a scalar input signal to logical vector.Binary-coded vector to scalar
— Decode a logical vector signal to scalar.Resize binary-coded vector
— Resize a logical vector while preserving the sign using two's complement method.Reverse binary-coded vector
— Reverse the bit index arrangement of a logical vector.
Note
When converting to a scalar value from a bit stream we will consider any input greater than 1 as a logical '1'. Similarly if the input bit is less than 0 (i.e. any -ve number) then it will be considered logical '0'.

Default:
Unipolar (magnitude) |
Number of vector elements in the input vector, specified as a positive real scalar.
By default, the least significant bit (LSB) is the first element of the vector (index 1). But you can also set the most significant bit (MSB) as the first element of the vector.
Dependencies
To enable this parameter, set Convert to
Binary-coded vector to scalar
