Convert empty table to zero

I produce a table in for loop that in some cases all elemtents of table might be empty. For example table.A= 0×1 empty double column vector.

How can I convert each element of empty table to zeoro?

? In such a case, all none of them are already zero. How many zeros would you want output ? And are all of your columns numeric?

@Walter Roberson

no they are not zero if they were zero I would recieve

table.A= 0

0

0

...

not A= 0×1 empty double column vector

Yes all of columns are numeric.

The table has 8 rows which are empty now and I want to make them zero instead of "empty"

Neither a table nor a matrix can have empty rows and non-empty rows. So already, we're struggling to understand what your data is stored as. Perhaps, it's a structure?

If something is empty, it means it has size 0 in at least one dimension. If you want to make that something non-empty that 0 dimension must be increased. Again, it's unclear from your question what it should be increased to.

Perhaps, showing the code that you use to create the table would help us understand.

@Guillaume:

Look at the table attached table:

You are right one of the dimensions are zero.

[Guillaume]

So, you have one table with 0 rows and 9 columns. Obviously, it's difficult to fill 0 rows with anything. The table could be expanded to a given number of rows, is that what you want to do? Why?

@Guillaume:

This table is being produced in a loop and I wanted to have zero table when I dont have any data because this table is being used later for other calculations but I changed my strategy and it is solved for now.

Thanks Guillaume for your help.

The answer might be

>> t = table.empty(0,3)
t =
  0×3 empty table
>> t{1,:} = 0
t =
  1×3 table
    Var1    Var2    Var3
    ____    ____    ____
     0       0       0  

but the question isn't clear enough to know.

I think the missing part is an if isempty test, which the user seems reluctant to code.
