minimam algorithm in matlab

To find the minimum value in an array in MATLAB, you can use a simple loop that compares each element of the array to the current minimum value. Here's an example algorithm:

main.m
% Define an example array
arr = [5, 2, 9, 1, 7];

% Initialise the minimum variable as the first element in the array
min_val = arr(1);

% Loop over the rest of the elements in the array
for i = 2:length(arr)
    
    % If the current element is less than the current minimum, update the minimum value
    if arr(i) < min_val
        min_val = arr(i);
    end
    
end

% The variable min_val now contains the minimum value in the array
disp(min_val);

In this example, we first define an array arr containing some example values. We then initialise the variable min_val as the first element in the array, since we don't yet know if any of the other elements are smaller. We then loop over the remaining elements in the array using a for loop, and check if each element is smaller than the current minimum. If it is, we update the min_val variable. At the end of the loop, the min_val variable contains the smallest value in the array, which we print out using the disp function.
