I have a cell such as
C={};
C{1,1}='A';
C{1,2}='B';
C{1,3}='C';
C{2,1}=[1 0 1;0 0 1;2 1 -1];
C{2,2}=[1 2 -1;-1 0 1;0 1 -1];
C{2,3}=[1 0 -1;-1 0 1;-1 1 -1];
C{3,1}=5/9;
C{3,2}=2/9;
C{3,3}=-1/9;
C =
3×3 cell array
{'A' } {'B' } {'C' }
{3×3 double} {3×3 double} {3×3 double}
{[ 0.5556]} {[ 0.2222]} {[ -0.1111]}
I want to remove a column which have the value -1<=x>=1 in all of the elements in the matrix at the second row. Such that
C =
3×2 cell array
{'A' } {'B' }
{3×3 double} {3×3 double}
{[ 0.5556]} {[ 0.2222]}

Unclear to me. Do the 3x3 arrays change? Can you highlight the values between -1 and 1 you are referring to?

C{2,2} also has -1<=x>=1.....isn't it?
What I mean is that all elements of 3x3 arrays (all 9 elements is -1<=x<=1). As for C{2,2}, it has 2 in one of the elements.

So what you mean is that you want to keep columns where at least one element (out of 9) lies outside of the specified bounds?

Try this
B=cellfun(@(x) sum(sum(abs(x)>1)),C(2,:),'uniformoutput',false)
B=cell2mat(B);
C(:,B<1)=[]
C =
3×2 cell array
{'A' } {'B' }
{3×3 double} {3×3 double}
{[ 0.5556]} {[ 0.2222]}

No problem! It only works for symmetric bounds. Just so you know.
