Convert Decimal to Binary Vector

Question

I need to convert a Decimal Number to a Binary Vector

For example, Something like this:

  length=de2bi(length_field,16);

Unfortunat

Answer 1

Are you using this for IEEE 802.11 SIGNAL field? I noticed "length_field" and "16". Anyway here's how I do it.

    function [Ibase2]= Convert10to2(Ibase10,n)

    % Convert the integral part by successive divisions by 2
    Ibase2=[];


    if (Ibase10~=0)

    while (Ibase10>0)

    q=fix(Ibase10/2);
    r=Ibase10-2*q;
    Ibase2=[r Ibase2];
    Ibase10=q;
    end


    else
    Ibase2=0;
    end

    o = length(Ibase2);
    % append redundant zeros
    Ibase2 = [zeros(1,n-o) Ibase2];
