I am trying to execute below code and I keep getting this error.

a=input('enter the value of mean: ');
P = 1
E=exp (-a)
R=[13,7,0.6]
R1=R(1)
R2=R(2)
R3=R(3)
for n=0:3
    R= R(n+1)
    Po=P.*R
    if  P < E
        N=n
    else
        n=n+1
    end

end

The error is

Error:Attempted to access R(2); index out of bounds because numel(R)=1.
Error in poisson (line 11)
    R= R(n+1)

Running perfectly fine on my machine, is this properly formatted in your program?

Answer 1

[the cyclist]

The first time through the loop over n, this line

R= R(n+1)

makes R into a scalar value. It is no longer the original vector of length 3. The next time through the loop, you try to access the 2nd element of the vector, but that no longer exists.

run on my matlab aftersome formating..thank u for help
