hex2poly

Convert hexadecimal character vector to binary coefficients

Syntax

b = hex2poly(hex)
b = hex2poly(hex,ord)

Description

example

b = hex2poly(hex) converts a hexadecimal character vector, hex, to a vector of binary coefficients, b.

b = hex2poly(hex,ord) specifies the power order, ord, of the coefficients that comprise the output. If omitted, ord is 'descending'.

Examples

Convert the hexadecimal polynomial '1AF' to a vector of binary coefficients. The coefficients represent the polynomial .

b = hex2poly('1AF')
b =

Convert hexadecimal '0x82608EDB' to a vector of binary coefficients. Specify that the binary coefficients are in ascending order.

b = hex2poly('0x82608EDB','ascending')
b =
