NtoFind=5;
[Mn,iMn]=mink(X,NtoFind);

[iB]

NtoFind=5;

[Mn,iMn]=min(out,NtoFind);

Undefined function 'min' for input arguments of type 'cell'.

NtoFind=5;

[Mn,iMn]=mink(out,NtoFind);

Undefined function or variable 'mink'.

'out' is my 1x45 cell

error is showing

Your example, while saying "cell" showed an ordinary array in brackets so I presumed that was what actually was. Dereference the cell array with "the curlies" -- see the documentation in the Getting Started section on accessing data in cell arrays to get the basics of syntax down.

[Mn,iMn]=mink(X,NtoFind{:});

I thik my matlab virsion is the problem, mine is R2015a. That is why 'mink' is not working.

Indeed, mink wasn't introduced until R2017b, I think...

The easiest coding way then is to use sort with the optional returned indices vector and select the first N
