i want to generalize and reduce following program into one loop

chx1=genx1 chx2=genx2 chx3=genx3 chx4=genx4 chx5=genx5

chy1=geny1 chy2=geny2 chy3=geny3 chy4=geny4 chy5=geny5

if ((gudx1>0) & (gudx2>0)) if (chx1==genx1) chx1= gudx2; end end

if ((gudx1>0) & (gudx3>0)) if (chx1==genx1) chx1= gudx3; end end

if ((gudx1>0) & (gudx4>0)) if (chx1==genx1) chx1= gudx4; end end

if ((gudx1>0) & (gudx5>0)) if (chx1==genx1) chx1= gudx5; end end

if ((gudx2>0) & (gudx3>0)) if (chx2==genx2) chx2= gudx3; end end

if ((gudx2>0) & (gudx4>0)) if (chx2==genx2) chx2= gudx4; end end

if ((gudx2>0) & (gudx5>0)) if (chx2==genx2) chx2= gudx5; end end

if ((gudx3>0) & (gudx4>0)) if (chx3==genx3) chx3=gudx4; end end

if ((gudx3>0) & (gudx5>0)) if (chx3==genx3) chx3=gudx5; end end

if ((gudx4>0) & (gudx5>0)) if (chx4==genx4) chx4= gudx5; end end

if ((gudx5>0) & (gudx1>0)) if (chx5==genx5) chx5= gudx1; end end

if ((gudx5>0) & (gudx2>0)) if (chx5==genx5) chx5= gudx2; end end

if ((gudx5>0) & (gudx3>0)) if (chx5==genx5) chx5= gudx3; end end

if ((gudx5>0) & (gudx4>0)) if (chx5==genx5) chx5= gudx4; end end

%y

if ((gudy1>0) & (gudy2>0)) if (chy1==geny1) chy1= gudy2; end end

if ((gudy1>0) & (gudy3>0)) if (chy1==geny1) chy1= gudy3; end end

if ((gudy1>0) & (gudy4>0)) if (chy1==geny1) chy1= gudy4; end end

if ((gudy2>0) & (gudy4>0)) if (chy2==geny2) chy2= gudy4; end end

if ((gudy2>0) & (gudy5>0)) if (chy2==geny2) chy2= gudy5; end end

if ((gudy3>0) & (gudy4>0)) if (chy3==geny3) chy3=gudy4; end end

if ((gudy3>0) & (gudy5>0)) if (chy3==geny3) chy3=gudy5; end end

if ((gudy4>0) & (gudy5>0)) if (chy4==geny4) chy4= gudy5; end end

if ((gudy5>0) & (gudy1>0)) if (chy5==geny5) chy5= gudy1; end end

if ((gudy5>0) & (gudy2>0)) if (chy5==geny5) chy5= gudy2; end end

if ((gudy5>0) & (gudy3>0)) if (chy5==geny5) chy5= gudy3; end end

if ((gudy5>0) & (gudy4>0)) if (chy5==geny5) chy5= gudy4; end end

ch1=[chx1 chy1] ch2=[chx2 chy2] ch3=[chx3 chy3] ch4=[chx4 chy4] ch5=[chx5 chy5]

i want to generalize above program and size of chx[1...5] and chy[1...5] may increase or decrease depend on user

Answer 1

[José-Luis]

And this is a prime example of why you should store your variables in a single matrix instead of with "numbered" names.

So the answer would be:

Place all gudxn and gudyn in a single array and loop through that array instead.

 gudx(1) = gudx1;
 gudx(2) = gudx2;

Ad nauseam...

[Mudasir Ahmed]

thanx sir, but i didnt get your point :( can u write it generalize form. i will be highly thankful to you

[Mudasir Ahmed]

sir i have made an array of that but how that array can be utilized in the above program is the main issue....

[José-Luis]

I'm sorry but I don't follow your logic. Are you testing for all possible permutations of gudx and gudy?

[Mudasir Ahmed]

A1=B1 A2=B2 A3=B3 A4=B4 A5=B5 %save values B in A

if ((X1>0) & (X2>0)) if (A1==B1) A1=X2; end end

if ((X1>0) & (X3>0)) if (A1==B1) A1=X3; end end

actually i want to pair in the following sense 1-2 1-3 1-4 1-5 2-3 2-4 2-5 3-4 3-5 4-5 5-1 5-2 5-3 5-4

pair with itself and decreasing one is not allowed except the final variable, who can pair with all variable below him except himself.

and 2nd main point is changing of any variable A1,A2,A3,A4,A5 is allowed only one time, means we cannot change a value of any variable twice or thrice.
