Matlab storing data and checking conditions

[thestrong]

Homework Statement

clear all;
close all;
totalanswers=zeros(100,4);
k= ;
flag =0;
for i =0:25
a=i;
if flag ==1
break;
end

and so forth for a,b,c,d, etc for a finite set of values all have the break values too.

x=[ a,b,c,d];

does some math calculationhere is a true statement to see if conditions are met

if (true == 1)
answers=[a,b,c,d]
if (answers ~=[previous ones])
flag = 1;
break;

The Attempt at a Solution

I need a way to store all the set of variables [a,b,c,d] that satisfy the conditions in totalanswers and to continue to run after one has been found.

ok, you need to clearly explain what the GOAL of this function is. after that we can help you with a solution.

clear all;
close all;
k=21;
flag =0;
allanswers=zeros(100,5);

while(allanswers(21,:) ~= [0,0,0,0,0])

%need to add a for loop and flags for each variabled added
for i =0:20
a=i;
if flag ==1
break;
end
for j=0:20
b=j;
if flag == 1
break;
end
for h =0:20
c= h;
if flag == 1
break;
end
for l=0:20
d=l;
if flag ==1
break;
end
for p=0:20
e=p;
%need to add variables when changing k
x=[a,b,c,d,e];

[Xcols, Xrows] = meshgrid(x, x);
G = Xcols-Xrows;
G = G.';
G(logical(eye(size(G)))) = [];
G=mod(G,k);
S=sort(G);

AllElements = zeros(1,k-1);
count = 1;
for i=1:k-1
AllElements(i) = count;
count = count+1;
end

true=isequal(S,AllElements);
if (true == 1)
%need to add variables when changing k
s=[a,b,c,d,e];
s=sort(s);
for i = 1:k
B=allanswers(i,:);
notlisted=isequal(s,B);
if (notlisted == 1)
allanswers(i,:)=s;
break;
end;
end;
flag = 1;
break;
end
end
end
end
end
end
endBasically I want the code to store all of the values into all answers and run until at least 21 "answers" are found instead of doing it manually. I am not sure what would be an effective method to run until 21 [a,b,c,d,e] answers that satisfy the module conditions I set.
