I have 13x1 cell. 1 to 7 rows are empty. I want to convert cell to matrix for rows 8 to 13 with different name for each cell{8,1}, {9,1}, {10,1}.....When I try cell2mat function as thetap=cell2mat(out{1,1}) it gives me error as
Cell contents reference from a non-cell array object.
Error in cell2mat (line 42) cellclass = class(c{1});
Error in Untitled3 (line 13) thetap=cell2mat(out{8,1});
Here are my code
out = cell(8,1);
for k = 8:13
myfrag = frag(:,:,k);
IM=[Int_m];
IM_frag=cat(1,IM,myfrag);
[i,j]=find(IM_frag(2:end,:)>0.1,1);
res=[IM_frag(1,j), min(IM_frag(2:3,j))];
out{k}=res;
thetap=cell2mat(out{8,1});
end

@sam moor: When you read the cell2mat documentation, you will learn that the input must be a cell array (as its name also implies). When you take the cell array out and use cell indexing like this out{8,1}) you are accessing whatever is inside that cell, which is clearly not a cell array itself. So you are passing something that is not a cell array to cell2mat. This will be an error. What do you expect to happen?
It seems that your usage of cell2mat is would be improved by reading the documentation, and revising how cell array indexing works:

I just want to change out{8,1}, out{9,1},......to matrix in different name.
