I can Not include my condition

Hi everybody,

I want to put a condition in my code, This is the code:

for i = 1:ne
       nodnum=zeros(1,nen);
       for j = 1 : nen
          check=Dof(:,1:nend)-ones(n,1)*Edof(i,(j-1)*nend+2:j*nend+1);
          [indx,dum]=find(check==0);
          nodnum(j)=indx(1);
       end       
          Ex(i,:)=Coord(nodnum,1)';
       if nsd>1
          Ey(i,:)=Coord(nodnum,2)';
       end
       if nsd>2    
          Ez(i,:)=Coord(nodnum,3)';
       end
    Le(i)=sqrt((Ex(i,1)-Ex(i,2))^2+(Ey(i,1)-Ey(i,2))^2+(Ez(i,1)-Ez(i,2))^2);

and this is that I want to put as a condition,

(Le(i)/Ep(i,6))>200

please help me out

Why don't you just put that condition to the specific place with an if structure?

Thank you Zoltán Csáti

I don't know how to do this because I want Ex,Ey,Ez obtain base on

(Le(i)/Ep(i,6))>200

Answer 1

[Thorsten]

 if Le(i)/Ep(i,6) > 200
   % do something
 end

Thank you Thorsten

I want Ex,Ey,Ez obtain base on

(Le(i)/Ep(i,6))>200

[Thorsten]

Ok. But Le depends on Ex, Ey, Ez, so you have to compute Ex, Ey, Ez first. Then you can set the values to NaN (not a number):

if Le(i)/Ep(i,6) > 200
  Ex(i,:)= nan(1, nen);
  Ey(i,:)= nan(1, nen);
  Ez(i,:)= nan(1, nen);
end

Dear Thorsten

I get this error, What should I do?

??? Undefined function or method 'nans' for input arguments of type 'double'.

Error in ==> coordxtr at 54
  Ex(i,:)= nans(1, nen);

Thank you very very much.

[Thorsten]

Sorry, should be

nan

I have corrected it above.

[Hamid]

Dear Thorsten

Ex,Ey,Ez are coordinates for elements, They must be numbers otherwise it has no meaning.

Thanks.
