Answer to Question #305533 in MatLAB for Mr Z

Question

On the same figure plot all four obtained powers in kW against time. Use different line styles for each power, e.g. solid line, dashed line, dotted line or dash-dot line. Add labels to all axes. Add title, legend and grid to the figure.

t = 0:1:100;    %Time Step

Load = 10;  % Ohms

P=[ ];       %power

Vel = [ ];   %Speed

Gear= [ ];   %Gear

SOC = [ ];   %Soc

V = [ ];     %Voltage

A = [ ];     %Current

for r=1:length(t)

    V(r)=100*rand;

    A(r) = V(r)/Load;

    P(r) = V(r) * A(r);

    Vel(r) = V(r)*rand();

    SOC(r) = Vel(r)*rand;

    Gear(r) = SOC(r)*rand();

end

scrsz = get(0,'ScreenSize');

Dim=0;

figure('Position',[scrsz(1)+Dim, scrsz(2)+Dim,scrsz(3)-20,scrsz(4)-100]);
