First off, did that work for you?

@(x)x{400} represents an anonymous function.
The parameter is defined by x. I passed In{1}(2:3) to x.
The cellfun then goes through both cells In{1}(2) and In{1}(3) and
grabs the {400} cell from each and returns them.

'un' is short for UniformOutput. see the cellfun documentation for
more details.
0 stands for false, as in I am asking for not UniformOutput and to
place output in individual cells

Do you understand that you keep asking the same question over and over
again?

Manipulate what I gave you to retrieve the "40th element from <4500x1>
from first 3 columns of <1x10>"

Assume cellarray is your <1x10><4500x1>
elementtoget = 40;
cellfun(@(x)x{elementtoget},cellarray(1:3))

Thanks, now I understand the principle
but it does not work I get this error

>> cellfun(@(x)x{40},tmp3(1:3))
??? Cell contents reference from a non-cell array object.

Error in ==> @(x)x{40}

Thank you
