How Can I determine minimum value in a double array?

Hello every one;

have an array :

vect =[ 2.6660 2.2852 10.0000 3.2617 10.0000 10.0000 9.8532]

I want to get the mininmum value as well as its position

here in this vector:

min = 2.2852

position = 2

please help me!

I need it to continue my program

Thank you

Don't use the built-in min function. It's second return argument will only return the location of the first occurrence of the min value. A more robust and general solution is to use min() in combination with find():

vect =[ 2.6660    2.2852   10.0000    2.2852 3.2617   10.0000   10.0000    9.8532];
minValue = min(vect(:))

minValue = 2.2852

% Find all the rows and columns where that value occurs:
indexes = find(vect == minValue)

indexes = 1×2

2 4

See how in this case, where the min occurred in two locations, it found both of them: one at vect(2) and another one at vect(4).

Subscript indices must either be real positive integers or logicals.

in the line minValue = min(vect(:))

clear('min'); % Get rid of your min variable you previously created.
vect =[ 2.6660    2.2852   10.0000    2.2852 3.2617   10.0000   10.0000    9.8532];
minValue = min(vect(:))
% Find all the rows and columns where that value occurs:
indexes = find(vect == minValue)

vect =[ 2.6660    2.2852   10.0000    3.2617   10.0000   10.0000    9.8532];

[vmin, idx] = min(vect)

vmin = 2.2852

idx = 2

thank you for your solution but an error display

Insufficient number of outputs from right hand side of equal sign to satisfy assignment.

"min" is a built in function; but you use it as a variable (strongly not recommended). Remove these lines and "clear all" to run your program.

min  = 2.2852
position = 2

I don't know where the problem is but the same error still display

I use matlab 2017a version
