hexToBinaryVector

R2026b

Convert hexadecimal value to binary vector

Syntax

binVal = hexToBinaryVector(hexNumber)

binVal = hexToBinaryVector(hexNumber,numberOfBits)

binVal = hexToBinaryVector(hexNumber,numberOfBits,bitOrder)

Description

This function is part of Data Acquisition Toolbox™, and converts hexadecimal data to binary data represented by a vector of 1s and 0s. To convert to binary data as a character vector, use the MATLAB^® functions hex2dec and dec2bin. See Hexadecimal and Binary Values.

binVal = hexToBinaryVector(hexNumber) converts a hexadecimal number to a binary vector.

binVal = hexToBinaryVector(hexNumber,numberOfBits) converts a hexadecimal number to a binary vector with the specified number of bits.

binVal = hexToBinaryVector(hexNumber,numberOfBits,bitOrder) converts a hexadecimal number to a binary vector with the specified number of bits in the specified bit ordering.

Examples

Convert Hexadecimal Number to Binary Vector

binVal = hexToBinaryVector('A1')

binVal =

  1×8 logical array

   1   0   1   0   0   0   0   1

Convert Hexadecimal Number with Leading 0 to Binary Vector

binVal = hexToBinaryVector('0xA')

binVal =

  1×4 logical array

   1   0   1   0

Convert Array of Hexadecimal Numbers to Binary Vector

binVal = hexToBinaryVector(['A1';'B1'])

binVal =

  2×8 logical array

   1   0   1   0   0   0   0   1
   1   0   1   1   0   0   0   1

Convert Hexadecimal Number to Binary Vector of Specific Bits

binVal = hexToBinaryVector('A1',12,'MSBFirst')

binVal =

  1×12 logical array

   0   0   0   0   1   0   1   0   0   0   0   1

Convert Cell Array of Hexadecimal Numbers into Binary Vector of Specific Bits

   1   0   1   1   0   0   0   1

Convert Hexadecimal Number into Binary Vector with LSB First

binVal = hexToBinaryVector('A1', [], 'LSBFirst')

binVal =

  1×8 logical array

   1   0   0   0   0   1   0   1

Input Arguments

hexNumber — Hexadecimal to convert to binary vector

hexadecimal value

Hexadecimal number to convert to a binary vector, specified as a character vector or string.

Data Types: char | string

numberOfBits — Number of bits to represent binary number

numeric

Number of bits to represent the binary number, specified as a numeric value. This is an optional argument. If you do not specify the number of bits, the function uses the minimum number of bits needed.

bitOrder — Bit order for binary vector representation

'MSBFirst' (default) | 'LSBFirst'

Bit order for the binary vector representation, specified as a character vector or string. Accepted values are:

• 'MSBFirst' — The first element of the binary vector is the most significant bit.

• 'LSBFirst' — The first element of the binary vector is the least significant bit.

Data Types: char | string

Output Arguments

binVal — Binary value

array of 1s and 0s

Binary value, returned as a logical array of 1s and 0s.
