does not show off the plot properly

Hi, I am trying to plot the following code, but when I hit plot command the constant acceleration line does not appear on the graph, is there something I am missing?? thanks in advance.

function []=plot_a(tmax,s0,v0,ac)
    t=0:0.1:tmax
    s=s0+v0.*t+0.5*ac*t.^2
    v=sqrt(v0^2+2*ac*(s-s0))
    ac=(s-s0-v0*t)/(0.5*t.^2)
    figure
    plot(t,ac)
    end

I found the working solution in another thread.

plot(t,ones(size(t)) * ac)

You have

      ac=(s-s0-v0*t)/(0.5*t.^2)

You used the mrdivide / operator, when you wanted the ./ divide operator
