How do I store the x's, the v's and the F's from this for loop into an array??? pls and ty

x=0; %position of the leaf in meters
v=.5; %the velocity of the leaf in meters/seconds
m=0.3; %mass of the leaf in kilograms
t=(0:0.05:3);
h=0.05;
int=0; %the intial time for graphing
%for
for I=(1:60) %Number of instances which is 0 to 3 seconds of steps of .05
%Plot
subplot(1,3,1)
plot(int,x,'.r') %Graph of position over time
hold on
subplot(1,3,2)
plot(int,v,'.r')
hold on
%Equations
F=0.2*(sin(x))*((x^2)+x); %Force equation
a=F/m; %acceleration equation
x=x+h*v;%New Position
v=v+h*a; %New Velocity
subplot(1,3,3)
plot(int,F,'.r')
hold on
int=int+0.05;
end

Hi,
I just modified your code so that you can store the values for x, v and F.
x=zeros(1,61);
v=zeros(1,61);
F=zeros(1,60);
x(1)=0; %position of the leaf in meters
v(1)=.5; %the velocity of the leaf in meters/seconds
m=0.3; %mass of the leaf in kilograms
t=(0:0.05:3);
h=0.05;
int=0; %the intial time for graphing
%for
for I=(1:60) %Number of instances which is 0 to 3 seconds of steps of .05
%Plot
subplot(1,3,1)
plot(int,x(I),'.r') %Graph of position over time
hold on
subplot(1,3,2)
plot(int,v(I),'.r')
hold on
%Equations
F(I)=0.2*(sin(x(I)))*((x(I)^2)+x(I)); %Force equation
a=F(I)/m; %acceleration equation
x(I+1)=x(I)+h*v(I);%New Position
v(I+1)=v(I)+h*a; %New Velocity
subplot(1,3,3)
plot(int,F(I),'.r')
hold on
int=int+0.05;
end
