Remove columns for a cell array

Z= {10x3000} 
how do i trim away 1000 columns to
Z={10x2000}

Answer 1

[per isakson]

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}
