Hello, I am trying to make a table using the fprintf function. I am using data from a for loop that I have created show below in the code. Also, the data comes from another function stepinfo. I want to have the columns named: K=1 K=10 K=30 K=50, and the rows equal to the same titles that stepinfo outputs in the command window. If you are able to help it will be most appreciated!

I don't know why my code is displaying weird, but here it is in this comment.

clc, clear, close all 
% OPEN LOOP
num = {1};
den = {[1 7 10 0]};
Gs = tf(num,den)
output = step(Gs);
figure(1)
stepplot(Gs)
% CLOSED LOOP 
for k = [1 10 30 50] % Values from question 3 
    num1 = {k};
    den1 = {[1 7 10 k]};
    Gcl = tf(num1,den1)
    output1 = step(Gcl);
    INFO = stepinfo(Gcl)
    figure(2)
    stepplot(Gcl)
    hold on 
end
legend('K=1','K=10','K=30','K=50');
fprintf(1, 'K=1 K=10 K=30 K=50')
fprintf(1, 'DATA', INFO')

Gs = 1 ------------------ s^3 + 7 s^2 + 10 s Continuous-time transfer function.

output = step(Gs);

hold on

for ik = 1:numel(k)

num1 = {k(ik)};

den1 = {[1 7 10 k(ik)]};

Gcl = tf(num1,den1);

output1 = step(Gcl);

INFO(ik) = stepinfo(Gcl);

stepplot(Gcl)

end

fprintf(1, ['%-15s\t' repmat('%f\t',1,numel(INFO)) '\n'], C{:})
