# MATLAB: Duplicate a matrix using nested for loops

duplicateduplicate matrixforfor looploopMATLABmatrix

In Matlab I have been trying to duplicate matrix A [2,4,1;6,7,2;3,5,9] to matrix B using nested for loops. I know the general format uses an algorithm within the loop ie.
 m=3 n=3 b=zeros(m,n) for i=1:m for j=1:n B(m,n)= *algorithm here* end end
I can not find an algorithm that would work for this matrix and I believe that it was designed this way on purpose. I have tried pulling numbers out of matrix A using
A=[2,4,1;6,7,2;3,5,9]for c=A(1,:)for d=A(2,:)for e=A(3,:)endendendB=[c;d;e]
but this just assigns the values for the last column of A to a 1×3 matrix B (B=[1;2;9]
I have also tried scouring the www for help with how to duplicated a matrix that is not algorithmic using nested for loops to no avail.
Any help or guidance would be much appreciated.

B = A;  % ?
[m,n] = size(A);B = zeros(m,n);for i1 = 1:m  for i2 = 1:n    B(i1,i2) = A(i1,i2);  endend_
