Error using plot, vectors must have the same length

I get the error

error using plot

"Vectors must be the same length"

when I run this code

F= 200 ; V=10 ; Q=1 ; k=0.1 ;

t(1)= 0;

c(1)= 0;

h=0.01;

Y= @(t,c) F/V-Q.*c/V-k.*c.^2;

for i= 1:200

t(i+1)= t(i)+h;

k1= c(i);

k2= c(i)+0.5*k1*h;

k3= c(i)+0.5*k2*h;

k4= c(i)+k3*h;

c(i+1)= c(i)+h*(k1+2*k2+2*k3+k4)/6;

end

plot(t,c)

Just check the sizes of t and c. You can check this on the variable window or on the command window as follows:

size(t) % will show dimensions for t
size(c) % will show dimensions for c

Plot requires a 1-on-1 correspondence, so for example, if t is 1x10, c MUST be 1x10

Hope you find this useful!
