One way
>> cac = cell(10,3000);
>> cac = cac(:,1:end-1000);
>> size(cac)
ans =
10 2000
>>
and another
cac = cell(10,3000);
cac(:,2001:end) = [];
whos cac
Name Size Bytes Class Attributes
cac 10x2000 160000 cell

Not sure what Z really is from your description. Maybe one of these will work for you:
Z(:,2001:end) = []; % assumes Z is a cell array of size 10x3000
or maybe
Z{1}(:,2001:end) = []; % assumes Z is a single cell with a 10x3000 array inside of it

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}
