Hi all
i am not able to find the indices for the minimum positive values inside a 2x7 cell. I would find the cell number (containing this minimum element) and its position inside the cell. For example in the first cell the minimum positive value have index [row,column]=[1,2].
This is my 2x7 cell:
C = {[5 0.0001;0 0.1],3,-2,2,3,[-0.1 5],[2 0.0001];[1 2],[0.0001 1],2,4,5,[1 -0.1],6};
Thank you for the help
Regards

You can always consider cellfun if you want to apply a function to every element of your cell. It might not be the fastest option though.
C = {[5 0.0001;0 0.1],3,-2,2,3,[-0.1 5],[2 0.0001];[1 2],[0.0001 1],2,4,5,[1 -0.1],6};
[rows,cols]=cellfun(@myfun,C);
function [row,col]=myfun(A)
A(A<0)=inf;%make sure it isn't the minimum
[~,idx]=min(A(:));
[row,col]=ind2sub(size(A),idx);
end

Sorry I had not specified very well in the last message. When i introduced the negative cell I wanted to take a step forward, redirecting myself to another goal, that is to find the value closest to zero. Thank you very much for the help

Hii Elda,You can use a for loops to go through each element in the cell and find indexes of minimum values for each cell element using the min() function.For more information and detailed examples, You can refer to : https://www.mathworks.com/help/matlab/ref/min.html
%You want to find minimum element and it's index in first Cell element
%M is the minimum value and [x,y] is the index of the minimum value in the cell element.
[M,I]=min(min(C{1,1}));
[x,y]=find(C{1,1}==M)
%To do this for the whole cell,You can use for loops to iterate through each element.
I hope this helps you.

ok something like that i suppose:
for i=1:2
for j=1:7
%You want to find minimum element and it's index in first Cell element
%M is the minimum value and [x,y] is the index of the minimum value in the cell element.
[M(i,j),I]=min(min(C{i,j}));
[x(i,j),y(i,j)]=find(C{i,j}==M(i,j));
%To do this for the whole cell,You can use for loops to iterate through each element.
end
end
But i want only >0 terms and this code include 0 as minimum element
