Finding index for minimum value in array

I need to find the index for the minimum value in pbest other than '0'. I got the value using the following code but I have the nan value in pbest in loops it is giving errors. Is there any other way to find the min value other than zero and also to find its index.Suggest with some points.

nk=1;n=6; pbest=[9;9.5;8;0;0]; pbest(~pbest)=nan; p1best=min(pbest); [wt,wr]=min(pbest);

Bathrinath, use

 [val,ind] = min(pbest(~ismember(pbest,0)));

or, the more general approach

 val = min(pbest(~ismember(pbest,0)));
 ind = find(val==pbest);

thank you sir

If you only need the second output from a function, you can use a tilde (~) to ignore specific outputs.

For example, you might only want the index containing the maximum value in a vector:density = data(:,2)
[~,ivMax] = max(v2)
densityMax = density(ivMax)

Try getting the index value of the minimum value in v2. Use this index to extract from density.

data
density=data(:,2)
[~,ivMax]=max(v2)
densityMax=density(ivMax)
density=data(:,2)
[~,ivMin]=min(v2)
densityMin=density(ivMin)
