how to create a vector with if-else statement

Hello,

I have the table below and the only problem is for the highlighted column. ! want it to show me either (over-damped or underdamped oscillation) by comparing it with the damp_coefficient instead of showing me the actual values. if the damping_coeff >= to the response then the column should show overd-damped. in this case it is all overdamped. i attach the simple code i created for this.

K = [200,400,800,800,800,800,800,400,400,400]'; % different sprring constants
 M = [0.5,0.5,0.5,0.5,0.5,0.5,0.5,1,2,3]';       % mass of each spring
 Bc = [4,4,4,8,16,32,40,4,4,4,]';                %damping_coefficient
 W = sqrt(K./M - (Bc.^2)./(4.*M.^2));            % frequency in rad/sec
 V = W./(2*pi);                                  %frequency in Hz
 T_end = (10.*M)./Bc;                             %the time at which oscillation stops
 z = 2*sqrt(K.*M);                               % condition for overdamp or underdamp
 for k = 1:length(z) 
     
     if Bc >= z
         disp('overdamped')
     else
         disp('underdamped')
     end
     
 end
 
table(K,M,Bc,z,W,V,T_end, 'variablenames', {'Spring_constant', 'mass',...
    'damping_coeff','response','omega ', 'frequency', 'decay_time'})

Bc(k) >= z(k)

[madhan ravi]

Or simply:

ix=Bc >= z;
B(ix)={'overdamped'};
B(~ix)={'underdamped'};
fprintf('%s\n',B{:})

Thanks for the answer, now that we generated a matrix of 'overdamped' how do I put it into the table code then?

[madhan ravi]

Just simply add that variable in the table() call and a valid variable name.

Note: Make sure the height of that variable is the same as the others. To alter it accordingly you’d nee to use .' .

Thanks, that totally worked
