how to replace each element in a array with the row of another array in matlab

To replace each element in an array with the corresponding row of another array, we can use indexing and loops in Matlab. Here's an example code that achieves this:

main.m
% create two sample arrays
A = [1 5; 3 7];
B = [9 8 7; 6 5 4];

% loop through each element in A
for i = 1:size(A, 1) % loop through rows
    for j = 1:size(A, 2) % loop through columns
        A(i,j) = B(i,:);
    end
end

disp(A) % output the updated array A

In this example, we first create two sample arrays A and B. Then we use nested loops to iterate through each element in A, and assign the corresponding row of B to that element. The size() function is used to determine the number of rows and columns in A, and the end keyword is used to specify the last index of an array dimension. Finally, we display the updated A array using the disp() function.
