matlab return the output of wrong function

Hi fellows,

I have encounted a super weird situation. I will try to explain it clearly.

I have defined several function, one of them is called maxmin.m. And this function would call another function called maxmin0. But when i call the function maxmin, the result is always the result from the function maxmin0. I don't know where is the problem. Becasue maxmin.m return the proper result when I test it by get rid of function form and run it as a normal .m file.

Please help me about this. This is the code for maxmin.m

   if true
    % 
function [ PF ] = maxmin(sub,DD)                             %risk parameter and low bounds 
d1=DD(:,1:3)-1;
d2=DD(:,4:6)-1;
edw=DD(:,7);
rn=size(d1,1);
lb1=sub(1);
lb2=sub(2);
lb3=sub(3);
r=sub(4);
[PF0,eu0]=maxmin0(sub,DD);
[PF1,eu1]=maxmin1(sub,DD);
[PF2,eu2]=maxmin2(sub,DD);
[PF3,eu3]=maxmin3(sub,DD);
[PF4,eu4]=maxmin4(sub,DD);
[PF5,eu5]=maxmin5(sub,DD);
[PF6,eu6]=maxmin6(sub,DD);
for i=1:rn
    eutotal(i,:)=[eu1(i);eu2(i);eu3(i);eu4(i);eu5(i);eu6(i)];
    if (0<=PF0(i,1))<=edw(i) && 0<=PF0(i,2)<=edw(i)
        PF(i,:)= PF0(i,:);
    else
        if(eu1(i)==max(eutotal(i)))
            PF(i,:)=PF1(i,:);
        elseif(eu2(i)==max(eutotal(i)))
            PF(i,:)=PF2(i,:);
        elseif(eu3(i)==max(eutotal(i)))
            PF(i,:)=PF3(i,:);
        elseif(eu4(i)==max(eutotal(i)))
            PF(i,:)=PF4(i,:); 
        elseif(eu5(i)==max(eutotal(i)))
            PF(i,:)=PF5(i,:); 
        elseif(eu6(i)==max(eutotal(i)))
            PF(i,:)=PF6(i,:);
        end

        end
    end

end

end

I am a little concerned about the way I define the output PF. It seems that matlab doesnt restore it...If I write maxmin as the m file form instead of function form, PF shows in the workspace and it is the right result. But if I call function maxmin, it returns the result from the function maxmin0.

Perhaps it is because you seem to type with so many errors that it doesn't know whether you mean maxmim, maxmin1, or maxmim1 - all of which you referred to. In addition you misspelled "weird" as "wired", "don't" as "dont", and "because" as "becasue", so I don't have any confidence that you aren't continuing your history of typographical errors in your code. Please make sure everything in your code is spelled exactly as it should be.

HI thanks for pointing out my typos. I am quite embarrassed about that. But I don't think this the problem comes from...

This is not proper syntax:

if (0<=PF0(i,1))<=edw(i) && 0<=PF0(i,2)<=edw(i)

You need something like:

if 0<=PF0(i,1) && PF0(i,1)<=edw(i) && 0<=PF0(i,2) && PF0(i,2)<=edw(i)
