4.231r=e^(-0.17232465r)
How to find r value? The soultion should be the point of intersection but, how to graph each side using MATLAB?

% fnc = (left side) - (right side)
fnc = @(x) 4.231*x - exp(-0.17232465*x);
% Visualize the fnc
figure
fplot(fnc)
Since it has a root between -5 ~ +5:
x0 = fzero(fnc,[-10 10]);
Then, the root is found to be:
>> x0
x0 =
0.2273

Hi
To find the value of r use: solve() in symbolic math or write a small code with the Newton Raphson method.
To plot bothe side of the equation, use a certain range of r and then plot.
