Multiplying one value in a matrix with a range of numbers (for loop) in matlab

Question

I am trying to write a simple code to replace one specific value in a matrix by a range of numbers. To be clearer, assuming I have my matrix G, which is a 3x3 matrix, I want to replace the (3,3) value in G with (3,3)+i where i is 1 - 10. I want to create essentially 10 new matrices where (3,3) is replaced by (3,3)+1 and then (3,3)+2 and then (3,3)+3 up to a value of 10. The original matrix is:

 G=[2 4 5; 6 7 8; 8 8 2] 

So, the output should a series of 10 new G matrices, so (3,3)+1 should give me

 G=[2 4 5; 6 7 8; 8 8 3] 

and for (3,3)+2 it should give me:

G=[2 4 5; 6 7 8; 8 8 4]

I know I can recode each matrix line by line but I want to create a loop to do this efficiently and to possibly change i to .001 increments rather than steps of 1.

I tried to do a simple code but I know I am missing the output part and I am having some bracket issues.

for i = 1:10;
    B[3,3]= B[3,3]+i;
end

Answer 1

It is quite simple:

1) Make a cell array: B = cell(1,10);

2) Make a matrix with 1 on position (3,3) and zeros elsewhere: M33 = zeros(3,3); M33(3,3) = 1; M33 = zeros(3,3); M33(3,3) = 1;

3) Loop through the numbers from 1 to 10 and save G+i*M33 to the i th entry of B :

for i = 1:10
  B{i} = G+i*M33;
end

You can now access the i th matrix as B{i} .
