MATLAB: Unable to delete variable

delete variableremotevarsundefined function

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.

If your structure Input always has fields Var1 and Var2, a simple solution would be like this.

function Var3 = TestFunction(Input)
Var3 = Input.Var1*Input.Var2;
end

Make sure to assign the revised struct back to the original variable. For instance, to remove field "field" from "s", use:

>> s = rmfield(s,field)
