How can I print the positions that a value occur in a row array?

If I have the matrix
A = [0, 2, 2, 6, 4, 3, 10]
and
Minimum = min(A)
How do I print the column positions that each minimum value occurs at? The statement below works only if there is only one minimum value present.
Assume X is the value of the position of the minimum value.
How can I print the positions if the minimum value occurs more than once?
fprintf('\nMinimum Temperature [degrees C]: %f (at position(s): %f)',Minimum, X);

Try this:
X = randi(9, 1, 40)
minTemperature = min(X);
indexes = find(X == min(X));
fprintf('Minimum Temperature of %.3f degrees C:\n', minTemperature);
fprintf(' at position: %d\n', indexes);
Sample results:
X =
Columns 1 through 21
2 7 5 5 8 8 5 3 2 8 9 9 6 1 1 2 1 7 2 6 8
Columns 22 through 40
6 4 8 3 3 8 5 3 7 2 9 3 1 1 7 8 7 7 9
Minimum Temperature of 1.000 degrees C:
at position: 14
at position: 15
at position: 17
at position: 34
at position: 35

I receive the following errors when running the code:
Index exceeds array bounds.
Array indices must be positive integers or logical values.
UPDATE:
I have fixed the issue. I kept the code that I was originally using except I separated the print statements into two like you did in the code you provided above. Thank you.
