oct2dec

R2026b

Convert octal to decimal numbers

Syntax

dec = oct2dec(oct)

Description

dec = oct2dec(oct) converts octal numbers in matrix oct to the decimal numbers in matrix dec, element by element. The rightmost digit is the least significant in both octal and decimal representations.

Examples

Convert Octal Matrix to Decimal Equivalent

Convert a 2-by-2 octal matrix to its decimal equivalent.

d = oct2dec([12 144;0 25])

d = 2×2

    10   100
     0    21

The octal number 144 is equivalent to 100 because $$144=1(8^2)+4(8^1)+4(8^0)=100$$.
