this is what I'm trying to plot
x=linspace(0,100,100);
a=5;
y=1/(abs(a*x)+1);
figure
plot(x,y)
how do I fix this error?

Maria, use
y = 1./(abs(a*x) + 1);
instead. Notice the dot right after the "1". This so-called elementwise division is necessary because x is a vector. See the documentation for more detail.
