I am plotting the only two variable by this command, plot(Ps11,​r1,'-*b','​linewidth'​,3); but showing that the ??? Error using ==> plot Data may not have more than 2 dimensions Error in ==> tw_df at 31 plot(Ps11,​r1,'-*b','​linewidth'​,3); please help me

clear all;close all; clc;
Ps11=-10:2:10;Pr1=10;Pr2=10;No=10^(-2);Rth=1;
Omg_1=1;Omg_2=1;Omg_3=1;Omg_4=1;Omg_5=1;Omg_6=1;r1=zeros(1: length(Ps11));
for a=1:length(Ps11)
    Ps1=Ps11(a);
    Ps2=Ps1;
    a1=(Ps1*Omg_1)/No;a2=(Pr1*Omg_2)/No;a3=a1*a2/(a1+a2);a4=No/(Ps1*Omg_5);

    for f=1:n+1
        x=xL+f*h;
        fvec1(f)=NumFun1(x,Ps1);
        fvec2(f)=NumFun2(x,Ps1);
    end

        f2=f2+fvec1(k);
        f4=f4+fvec2(k);
    end
    Iinterval_1=(h/3)*(fvec1(1)+4*f1+2*f2+fvec1(n+1));
    Iinterval_2=(h/3)*(fvec2(1)+4*f3+2*f4+fvec2(n+1));

In this there are two functions
first function is: 
function fun1=NumFun1(x,Ps1)
Pr1=10;No=10^(-2);Rth=1;
Omg_1=1;Omg_2=1;Omg_5=1;Omg_6=1;
Ps2=Ps1;
a1=(Ps1*Omg_1)/No;a2=(Pr1*Omg_2)/No;a3=a1*a2/(a1+a2);a4=No/(Ps1*Omg_5);
a5=(Omg_6*Ps2)/(Omg_5*Ps1);a6=2^(2*Rth);a8=(a6/a3)+a4;
fun1=(a4*exp(-a8*x))/(a5*x+1);
end
and second function is:
function fun2=NumFun2(x,Ps1)
Pr1=10;No=10^(-2);Rth=1;
Omg_1=1;Omg_2=1;Omg_5=1;Omg_6=1;
Ps2=Ps1;
a1=(Ps1*Omg_1)/No;a2=(Pr1*Omg_2)/No;a3=a1*a2/(a1+a2);a4=No/(Ps1*Omg_5);
a5=(Omg_6*Ps2)/(Omg_5*Ps1);a6=2^(2*Rth);a8=(a6/a3)+a4;
fun2=(a5*exp(-a8*x))/(a5*x+1)^2;
end

I got my problem and sole it myself. Problem is this only "r1=zeros(1: length(Ps11));" instead of this command we can keep correct command "r1=zeros(1, length(Ps11));" Thanks to KSSV to try to solve it.

YOur Ps11 is 1X11 and r1 is n dimensional matrix.....

[Shashibhushan Sharma]

sorry sir, r1 is also 1X11 matrix. Please see it carefully and help me. I tried.
