index the minimum value in a matrix in matlab

To index the minimum value in a matrix, you can use the find function in Matlab. First, use the min function to determine the minimum value in the matrix, and then use the find function to obtain the indices of the minimum value in the matrix.

Here is an example code snippet:

main.m
% create a matrix
A = [3, 5, 1;
     2, 7, 9;
     8, 4, 6];

% find the minimum value in the matrix
min_val = min(min(A));

% find the indices of the minimum value in the matrix
[row, column] = find(A == min_val);

In this example, the min function is used twice to obtain the minimum value in the entire A matrix. The find function is then used to obtain the indices of the minimum value in the matrix, which are stored in the row and column variables.
