How can I find from an input vector the position of the number that deviates the most from the average of the values of the vector.

averageOfVector = mean(vector);
Now, assuming the input vector, inputVector, has positions in it, what do those positions deviate FROM by more than averageOfVector? Is there a third vector, like
deviations = inputVector - thirdVector;
firstPosition = find(deviations > averageOfVector , 1, 'First');

I think i need to use mean to find the average and then compare it with all the values and show the position of the value that deviates the most from that average, it can be negative but also positive.

Sounds like a class assignment. Hint: use the max() function and look at both return arguments. Also look at the abs() function.

You want to know the location of the MAXimum ABSolute difference between x and its MEAN ?
