整数转化为二进制原码

function y = dec2yuanma(x,N)
   %1<=N<=53
    y=zeros(N,length(x));
    for i=1:length(x)
            if x(i)<0
                x(i)=2.^(N-1)-x(i);
            end
            d=flip(dec2bin(x(i)));
            b=zeros(N,1);
            for j=1:length(d)
                b(j)=str2num(d(j));
            end
            y(:,i)=b;
    end   
end

整数转化为二进制补码

function y = dec2buma(x,N)
   %1<=N<=53
    y=zeros(N,length(x));
    for i=1:length(x)
            if x(i)<0
                x(i)=2.^N+x(i);
            end
            d=flip(dec2bin(x(i)));
            b=zeros(N,1);
            for j=1:length(d)
                b(j)=str2num(d(j));
            end
            y(:,i)=b;
    end   
end
