use the secant method to determine resting membrane potential (e m) for j+ = 0.9 mm/min to an error tolerance of tol and an initial guess of x1se and x2se in the ghk equation in matlab in matlab

main.m
function result = ghk_eqn(x)
    % Given parameters
    j_plus = 0.9; % mm/min
    tol = 1e-6; % error tolerance

    % Rest of the GHK equation
    % Implement the rest of the equation using the given parameters
    % You can use variables such as j_plus, tol, etc. in this function

    % Calculate the result
    result = % Implement the GHK equation using the given parameters
