Dear all,

I need to make table of four rows such that I can sort it and turn it to a table contain the strings of the rows because I want to rank it, and apply GA on it and I used fprintf before but it is not like table,,,fprintf(' %f %f \n',f,l),,, I should use table, but I have problem how do it could you please help me, thanks in advance

for j=1:4
q1=[25.8862  3.0912; 4.9390   44.5138; 25.3633    5.6858; 4.5108   48.9112];
q2=[11.5684  5.9243; 1.6695   41.9517; 24.5223   29.9721; 32.6509   23.0566];
r=sqrt((q1(j,1)-q1(j,2))^2+(q2(j,1)-q2(j,2))^2);
f=h/2;l=f/3;
format LONG
A=[f,l];s = regexprep(sprintf('%011.6f',A),'[.\s]','');end

imola - please format the above code so that it is readable. Highlight the code portion and press {} Code.

By table do you mean matrix? What would the four rows be since you have to input parents p1 and p2? How would you sort it i.e. what is the sorting criteria?

table is a new data type as or R2013b where you can mix data types like strings and numbers by column. A little more restricted than cell arrays but a mot easier to deal with if all your columns are the same data type for every row in that column.

In my answer I used a cell array, and a matrix (probably the easiest form).

在 MATLAB Online 中打开

Try this:

clc;    % Clear the command window.
clear;  % Erase all existing variables. Or clearvars if you want.
workspace;  % Make sure the workspace panel is showing.
format long g;
format compact;
fontSize = 13;
p1=[25.8862  3.0912; 4.9390   44.5138; 25.3633    5.6858; 4.5108   48.9112];
p2=[11.5684  5.9243; 1.6695   41.9517; 24.5223   29.9721; 32.6509   23.0566];
for k = 1:4
  d=sqrt((p1(k,1)-p1(k,2))^2 + (p2(k,1)-p2(k,2))^2);
  a=d/2;
  b=a/3;
  s{k} = sprintf('%011.6f, %011.6f', a, b);
end
celldisp(s)

In the command window:

s{1} =
0011.741677, 0003.913892
s{2} =
0028.234821, 0009.411607
s{3} =
0010.209118, 0003.403039
s{4} =
0022.712585, 0007.570862

Since your strings are all the same length, you can make s a character array instead of a cell array if you want.

s = char(4, 24);
for k = 1:4
  d=sqrt((p1(k,1)-p1(k,2))^2 + (p2(k,1)-p2(k,2))^2);
  a=d/2;
  b=a/3;
  s(k,1:24) = sprintf('%011.6f, %011.6f', a, b);
end
s
s =
0011.741677, 0003.913892
0028.234821, 0009.411607
0010.209118, 0003.403039
0022.712585, 0007.570862
