Plotting results on log scale

So i wrote this program but need to plot the rmin results but cant get it to work...i tried plot(1:100,rmin) but dont get the desired result...i only want to plot the rmin values

for j=1:1000

x = x + vx*dt;

vx = vx - sign(vx - hw)*Cd/m*(vx -hw)^2*dt;

y=y + vy*dt;

vy = vy +(-g-sign(vy)*Cd/m*vy ^2)*dt;

r(j)=((((x-xt)^2)+((y-yt)^2))^(1/2));

rmin(i)=min(r);

vx=0;

vy=0;

x=0;

y=0;

end

end

newp=[rmin;m;Cd;v0;theta]';

The rmin values of newp is what i want plotted on a log scale

Hi Omar,

To plot the values in logarithmic scale, you can use loglog, semilogx, and semilogy plot functions.

If you are not sure, which plot to use, you can go to the Plots option in the MATLAB toolstrip and then select a workspace varaible, that provides you which plot is suited.

Hope this helps,
