Getting mutliple lines into a legend from a for loop that provides different values

Below is my code, im trying to get each of the lines on the plot onto the legend but am unsure how to go about it? I know i can just type it out manually for each gamma value e.g legend('2\gamma = 0','2\gamma = 1','2\gamma = 3',) but i would like a method that automatically adjusts to any variations i may make to gamma

clear all
for gamma = [0,0.5,1.5]
    % Parameters
    k = 5; % constant
    zeta = 2*gamma; %Damping Coefficient
    x_initial = 0.1; %Initial Position
    v_initial = 0; %Initial Velocity
    dt = 0.0001; % Time Step
    t_vector = 0:dt:10; % Time Vector
    
    x(1) = x_initial; %Initial position
    v(1) = v_initial; %Initial velocity
    
    %for loop
    for n= 1:length(t_vector)-1
        xslope = v(n);
        x(n+1) = x(n) + xslope*dt;
        vslope = -zeta*v(n) -k*x(n);
        v(n+1) = v(n) + vslope*dt;
    end
    
    %plotting the graph
    a = -zeta*(-v) -k*(-x);
    plot(t_vector,a)
    hold on;
end

title("Damped Simple Oscillator");
xlabel("Time");
ylabel("Amplitude");
lgd = legend(sprintf("2\\gamma = %d", zeta));
title(lgd, "\zeta")
grid on;
hold off;

Answer 1

[Voss]

all_gamma = [0 0.5 1.5];
for gamma = all_gamma
    % your code
end
lgd = legend(sprintfc('2\\gamma = %d',2*all_gamma));

This works amazing thank you. Had to change %d to %g to eliminate scientific notation for decimals.

Answer 2

[Matt J]

lgd = legend('2\gamma='+string(2*[0,0.5,1.5]));

[Adam Lacey]

Thanks thats definitely more succinct than what i had but still requires manually updating for each change in gamma value. Is there an automatic way?
