going from command window (as script) to function

the program is working perfectly but when i am changing it to function the follwing error is beeing displayed:

     [Parent1index, Parent1Position, alldcel] = Parent1n(TotalnoOfGrids, noOfNodes, Penalties, test)
     ??? Index exceeds matrix dimensions.

     Error in ==> Parent1n at 10
     [~,index]=min(alldcel{t});

ok with this code the functiion worked:if Penalties{t}(r)> 0; alldcel {t}(r)=alldcel{t}(r); else alldcel {t}(r)=inf; but interchanging if statement with else did not

Because alldcell{t} may not exist for some values of t if the condition to assign values to it in

if Penalties{t}(r)== 0;
   alldcel{t}(r)=inf;
end

is never satisfied. Assume for some t that all values of Penalties{t} are different than zero. Then you would never assign inf to alldcell{t}. That means, you are only extending the cell array alldcell when Penalties{t} is zero for some r. If the condition is never satisfied, alldcell{t} will not exist and asking for it will give you a cell array error.

You should at least initialize it using alldcell = cell(TotalnoOfGrids,1).

Also, comparing for equality to zero using a==0 is not a good idea. You should use abs(a)<tol for some small value tol.
