If you want to delete more than one rows of cell you can ...
a= cell(5,5)
a =
5×5 cell array
{0×0 double} {0×0 double} {0×0 double} {0×0 double} {0×0 double}
{0×0 double} {0×0 double} {0×0 double} {0×0 double} {0×0 double}
{0×0 double} {0×0 double} {0×0 double} {0×0 double} {0×0 double}
{0×0 double} {0×0 double} {0×0 double} {0×0 double} {0×0 double}
{0×0 double} {0×0 double} {0×0 double} {0×0 double} {0×0 double}
a([2,3],:)=[]
a =
3×5 cell array
{0×0 double} {0×0 double} {0×0 double} {0×0 double} {0×0 double}
{0×0 double} {0×0 double} {0×0 double} {0×0 double} {0×0 double}
{0×0 double} {0×0 double} {0×0 double} {0×0 double} {0×0 double}

a is the cell array
b=find(cellfun(@(x) size(x,1)<3,a)==1);
while ~isempty(b)
a(b(1))=[];
b=b-1;
b(1)=[];
end

No, this checks for vectors less than 3 elements anywhere in the cell array.
The == 1 is redundant because the places that satisfy <3 will already return 1 and the other places will return 0 and find() automatically checks for non-zero. The code there is sort of like
find((x < 3) == true)
when you could just use
find(x < 3)
