Error when creating an empty Table

I faced the following error when i use "table" command to create and empty table:

my_results = table

Error using ones

Invalid default value for property 'metaDim' in class 'table':

Size inputs must be scalar.

Error in all (line 68)

sz = [sz,ones(1,DIM-length(sz))];

Error in matlab.internal.tabular.private.metaDim (line 45)

if ~(isCharStrings(labels,true) && all(strlength(labels) > 0, 'all')) % require cellstr, whitespace, but not empty allowed

any suggestion?

To preallocate a table see the documentation section on Specify Size and Variable Types since an empty table nevertheless has specific requirements for its construction.

Thank you for your prompt reply.

That's right. preallocate /define table would help. But without pre-defining the raw /colum Matlab offers another way: "Create an empty table" . However, running the example from Matlab-help generates the same error.

I cannot find ‘Create an empty table’ in the R2021b documentation for table, so that option may have been removed. I can only find the documentation section I linked to.

Thats' right. i developed the scpirt in 2018b and faced this error in 2021b. Thank you for your help!

My pleasure!

Reza, if that's really what you get in the command window, and you have not left anythng out, then you either have something else named "table", or you have something seriously wrong with your MATLAB install.

Thank you Peter for your comments.
