I have matrix A and B of same order. I want to find minimum nonzero value of matrix A and its location. If A has more than one same minimum values than minimum should be selected from B matrix from the given location of matrix A. How I get one minimum value from matrix A and B and its lOcation in a loop. Thanks

As per your query, you can find the minimum value of matrix A and the minimum value of matrix B at those locations using the following method -
A = [1 0 3; 2 0 5; 0 4 0];
B = [7 8 9; 6 5 4; 3 2 1];
% Initialize the minimum value and its location
minValueA = Inf;
minLocationA = [0, 0];
% Loop through each element of matrix A
[row, col] = size(A);
for i = 1:row
for j = 1:col
% Check if the element is nonzero and smaller than the current minimum
if A(i, j) ~= 0 && A(i, j) < minValueA
% Update the minimum value and its location
minValueA = A(i, j);
minLocationA = [i, j];
end
end
end
% Initialize the minimum value from matrix B
minValueB = Inf;
% Loop through each element of matrix A again
for i = 1:row
for j = 1:col
% Check if the element of A is equal to the minimum value of A
if A(i, j) == minValueA
% Check if the corresponding element in B is smaller than the current minimum
if B(i, j) < minValueB
% Update the minimum value from matrix B
minValueB = B(i, j);
end
end
end
end
% Display the minimum value of A, its location, and the minimum value of B
disp("Minimum Value of A: " + minValueA);
disp("Location in A: " + minLocationA);
disp("Minimum Value of B at the location: " + minValueB);
