How can I put an output from the display function in a table?

Hi there,

I am wondering how I can put the results using the display function into a table.

This is the code:

Section = ['254 x 254 x 73';'254 x 146 x 31';'254 x 146 x 31';'254 x 254 x 73';'254 x 254 x 73';'152 x 152 x 51';'152 x 152 x 51';'152 x 152 x 51';'203 x 203 x 46';'203 x 203 x 52'];
h = [254.1; 251.4; 251.4; 254.1; 254.1; 170.2; 170.2; 170.2; 203.2; 206.2];
b = [254.6; 146.1; 146.1; 254.6; 254.6; 157.4; 157.4; 157.4; 203.6; 204.3];
tw = [8.6; 6.00; 6.00; 8.6; 8.6; 11.00; 11.00; 11.00; 7.2; 7.9];
tf = [14.2; 8.6; 8.6; 14.2; 14.2; 15.7; 15.7; 15.7; 11.00; 12.5];
r = [12.7; 7.6; 7.6; 12.7; 12.7; 7.6; 7.6; 7.6; 10.2; 10.2];

E = 0.81;

for i = 1:length(h)
Cw(i) = h(i) - 2*(tf(i)) - 2*(r(i));
c_w(i) = Cw(i)/(tw(i));
if c_w(i) < 72*E
   disp("Web is class 1")
else
    disp("Web is not class 1")

end
Cf(i) = b(i)/2 - tw(i)/2 - r(i);
c_f(i) = Cf(i)/tf(i);
if c_f(i) < 9*E
    disp("Flange is class 1")
elseif c_f(i) < 10*E
     disp("Flange is class 2")
else
    disp("Section is Class 3 or 4")
end
end

I would like to have a table with the 'sections' displaying "Web is class 1" or "Flange is class 2". MATLAB doesn't seem to let me assign a variable to the display function, so I can't work out how to put the data into a table.

Can someone help please?

Create a table, fill the data and display it.

doc table

Brilliant, that is amazing. Thanks VBBV!

As @Fangjun Jiang mentioned, you can find more info about table function in help reference. e.g to give names to table variablenames , access data from tables, change the order of variables in table etc

[Scott Banks]

Great! Thanks again.

@Scott BanksAn alternative to disp and table functions is using fprintf function as below

Section = ['254 x 254 x 73';'254 x 146 x 31';'254 x 146 x 31';'254 x 254 x 73';'254 x 254 x 73';'152 x 152 x 51';'152 x 152 x 51';'152 x 152 x 51';'203 x 203 x 46';'203 x 203 x 52'];
h = [254.1; 251.4; 251.4; 254.1; 254.1; 170.2; 170.2; 170.2; 203.2; 206.2];
b = [254.6; 146.1; 146.1; 254.6; 254.6; 157.4; 157.4; 157.4; 203.6; 204.3];
tw = [8.6; 6.00; 6.00; 8.6; 8.6; 11.00; 11.00; 11.00; 7.2; 7.9];
tf = [14.2; 8.6; 8.6; 14.2; 14.2; 15.7; 15.7; 15.7; 11.00; 12.5];
r = [12.7; 7.6; 7.6; 12.7; 12.7; 7.6; 7.6; 7.6; 10.2; 10.2];

E = 0.81;

for i = 1:length(h)
Cw(i) = h(i) - 2*(tf(i)) - 2*(r(i));
c_w(i) = Cw(i)/(tw(i));

if c_w(i) < 72*E
   T1{i} = "Web is class 1";   
   fprintf('    ')
   fprintf('\nc_w                  section')
   fprintf('------------------------------------')
   fprintf('%2.2d\t %s\n',c_w(i),T1{i})
else
   T1{i} = "Web is not class 1";
   fprintf('%2.2d\t %s\n',c_w(i),T1{i})
end

Cf(i) = b(i)/2 - tw(i)/2 - r(i);
c_f(i) = Cf(i)/tf(i);

if c_f(i) < 9*E
    T2{i} = "Flange is class 1";    
    fprintf('    ')
    fprintf('\nc_f                 section')
    fprintf('-----------------------------------')
    fprintf('%2.2d\t %s\n',c_f(i),T2{i})
elseif c_f(i) < 10*E
     T2{i} = "Flange is class 2";
     fprintf('%2.2d\t %s\n',c_f(i),T2{i})
else
    T2{i} = "Section is Class 3 or 4";
    fprintf('%2.2d\t %s\n',c_f(i),T2{i})
end

end
