MATLAB: Storing outputs from loop iterations into a 1 dimensional array

Question

Hi,

I need help storing iterations from a for loop into a 1 dimensional array in MATLAB. Here's my script:

M=input('Enter matrix M ');

K=input('Enter constant vector K ');

n=input('Enter number of unknown forces n ');

for i=1:n

    CramerCalc(M,K,i);
end

And my function:

function [ F ] = CramerCalc( M,K,i )

D=det(M);

Mat=M;

Mat(:,i)=K(:);

C=det(Mat);

F=C/D;

V(i,:)=[F]

What I'm getting: V =

134.1989

V =

         0
  169.7423

V =

         0
         0
  120.0259

V =

     0
     0
     0
     0

V =

         0
         0
         0
         0
   60.0259

V =

         0
         0
         0
         0
         0
  120.0259

How can I put it all into one?

Also, if you can, could you please teach me how to code the for loop to store each answer under different names? For example, the answer from the first iteration would be stored as F1, the second as F2, so on and so forth.

Finally, how would I be able to combine the 2 previous things so that the array would come out like this: V=[F1 F2 F3 F4 F5 F6]

Thank you in advance for any help!

Answer 1

Take this line out of your function file (where it seems to be now):

V(i,:)=[F]

and put it in your loop (with a slight modification):

for i=1:n
    V(i,:) = CramerCalc(M,K,i);
end

See if that helps.
