Assuming your cell is made up of vectors. Every cell{i} is a numerical vector itself.
this code should work:
for i=1:10
a=cell{i};
for j=1:length(a)
if a(j)==1||a(j)>25 %(example conditions put your own)
a(j)=0;
end
cell{i}=a;
end
end
Hope it helps.
PS. this also does it without using double loop:
for i=1:10
a=cell{i};
ind=find(a==1|a>25) %(example conditions put your own)
a(ind)=0
cell{i}=a;
end
