when run my code matlab give me error why?

n1 = 0:50; f1 = 0.05; phase1 = 0; peak = 1.0; A1 = 1.0; arg1 = 2*pi*f1*n1 + phase1; u=255; x1 = A1*sawtooth(arg,peak); Xc1 = (log(1 + 255.*abs(x1)) ./ log(1+u)) .* sign(x1)

L = 2^4; q = 2/L; y1 = q.*round(Xc/q);

exp1 = ((-1 + (1+u).^abs(Y1)) ./ u);

stem(n,exp1)

在 MATLAB Online 中打开

n1 = 0:50; 
f1 = 0.05;
phase1 = 0; 
peak = 1.0; 
A1 = 1.0; 
arg1 = 2*pi.*f1.*n1 + phase1;
u=255; 
x1 = A1.*sawtooth(arg1,peak); 
Xc1 = (log(1 + 255.*abs(x1)) ./ log(1+u)) .* sign(x1)
L = 2.^4; 
q = 2./L;
y1 = q.*round(Xc/q);
exp1 = ((-1 + (1+u).^abs(y1)) ./ u);
stem(n1,exp1(1:numel(n1)))
