@Walter, this reflects a recent change in the documentation policy for some of our products. Try accessing the above incognito or inprivate browsing mode.

The documentation is not hidden, but the product description is not.

But anyone, new or otherwise, with a MATLAB question should not be expected to know of the existence of this product or any of the 90 other products MathWorks makes.

This miss-classification is genuine and other forum contributors to help clean up.

Can you elaborate? argmin means 'argument of the minimum' of a function. Which means you want to perform an optimization.

Check out the following link for information about optimization in base matlab:

To return k, the index of the minimum value of V (also called the argmin of V), do this: k = find(V==min(V))

@Mary Nahill: use the second output of min or max.

in my project am having ranking criteria is c(i)=w(i). "i represents 1 to 50". so 'c' contains 50 elements. and now in my algorithm says these 50 elements further to reduce using ranking procedure and eliminate the smallest rank value. for these elimination process in my algorithm given a formula f=argmin(c).here how to writhe these function in matlab. when i try to write these function in matlab it shows the error.

>> f=argmin(C) ??? Undefined function or method 'argmin' for input arguments of type 'double'.
