Using for loop

Hi

I have written a simple code which goes like this;

for 
  i=1:length(b)

    Class= vlookup(MOD(1:end , 14:15),MOD(i,1),2,1);

end

The problem is that Class only retains the last value (i.e. for the last value of b). I need to put all the values of class after it looks up for 1 = 1:length(b).

So my required answer should be an array with same dimensions as b.

Best regards

EDITED
Class(:,i)= vlookup(MOD(1:end , 14:15),MOD(i,1),2,1);

Hi GA I have tried the

Class(i)= vlookup(MOD(1:end , 14:15),MOD(i,1),2,1);

however it gives error Error in ==> Cluster_treatment at 3

Complete statement that i am using is as

for i=1:length(MOD);

    % Giving Met class to each match up
    Class(i)= vlookup(MOD(1:end , 14:15),MOD(1327,1),2,1);

end

PS.

I have checked

vlookup(MOD(1:end , 14:15),MOD(1,1),2,1)

in the command window and it works fine for all values of i.

what is the size and type of output of vlookup()?

[Walter Roberson]

What is the error that it is showing?

[Muhammad]

@ G A

vlookup should give a single column array of 29441 rows (29441= length (b)also equal to length (MOD)

[Muhammad]

@ Walter Roberson

Error in ==> Cluster_treatment at 3

Class(i)= vlookup(MOD(1:end , 14:15),MOD(1327,1),2,1);

plz see code in question 1 .

[G A]

if vlookup() gives an column-array of length(b) in one cycle , then, perhaps, within the for-loop you have to try

Class(:,i)= vlookup()

See above edited

[Walter Roberson]

"Error in ==> Cluster_treatment at 3" says where the error _is_, but does not say what the error is. For example is it complaining that the number of dimensions in the left hand side must match the number of dimensions in the right hand side?

hai. you try saving the value of class in an array, so that each time loop runs it will be automatically saved in that.

Hi Pramod

Thanks. I think i have tried same in answer 2. But its giving error.
