Unable to delete variable

I have a variable (zeta) that I want to delete from a structure (A).

I tried to use the removevars() function:

A1 = removevars(A, ('zeta'));

and got the following error message:

"Undefined function 'removevars' for input arguments of stype 'struct'."

When I used which removevars it showed me the path for the function (C:\Program Files\MATLAB\R2019a\toolbox\matlab\datatypes\@tabular\removevars.m % tabular method) so why is it not working?

removevars will only work on tables, not on structs. Use rmfield to remove a field from a struct.
