Why do i receive "Error using plot. Data cannot have more than 2 dimensions"

I had been trying to plot the equations for S,I and R but i am receiving this "Error using plot.Data cannot have more than 2 dimensions"

Here is the code:

t=18;
N=100;
S0=0.8;
I0=0.2;
R0=0;
beta = 100/365; 
mu = 0.014/365; 
gamma = 0.2/365; 
sigma = 50/365;
m = 0.0001/365;
a=0.5;
b=0.9;
NA = 3;
NL = 7;
NS = NA^NL;
C = 2*NL*NS;
d=7;

S=zeros(1,C);
I=zeros(1,C);
R=zeros(1,C);
K=zeros(1,C);
s=zeros(1,C);
S(1)=S0;
I(1)=I0;
R(1)=R0;
lambda=0.1;
y=0.01;
y1=0.25;   
lambda1=0.76;

for t1=1:1:18
    K(t1+1)=t1;
    kmax=NS;
    imax=NL-1;
    S=zeros(imax,kmax,t1);
    R=zeros(imax,kmax,t1);
    for k=1:1:kmax
        for i=1:1:imax
            S(i,k,t1+1)=S(i,k,t1)+mu*(1-S(i,k))-S(i,k)*lambda+gamma*R(i,k);  
            I(i,t1+1)=I(t1)+beta*I(i)*y-sigma*I(i)+N*m*y1;
            R(i,k,t1+1)=R(i,k,t1)+S(i,k)*lambda1-(gamma+mu)*R(i,k);
        end
    end
end
plot(K,S,'r.-');
hold on
plot(K,I,'b-o')
hold on
plot(K,R,'k-d')
hold off

Check the dimensions of K and S.. K is 1x30618 and S is 6x2187x19 . You cannot plot them.

Thankyou.

You have variables with three indices. plot() is a tool for 2d line plots,and cannot handle 3d arrays.

When you have 3d arrays, your options include:

• slice()
• isosurface()
• volumeViewer()
• animations

You are trying to plot a cuboid of data, which is a problem even in 3d, as outer parts of the data hide inner parts.
