Undefined function 'diff' for input arguments of type 'table'

Dear Members,

I am facing following error when running my MATLAB code. Please advice the solution for this.

>> ind1=find( diff(daily_stk(:,2)) ~= 0 ); % row number
Undefined function 'diff' for input arguments of type 'table'.
 
daily_stk.Properties
 
ans = 
  TableProperties with properties:
                  Description    :     ''
                  UserData       :     []
          DimensionNames  :     {'Row'  'Variables'}
           VariableNames    :     {'yyyy'  'mm'  'dd'  'vwretd'}
    VariableDescriptions    :     {}
           VariableUnits        :     {}
      VariableContinuity    :     []
                RowNames    :     {}
        CustomProperties    :     No custom properties are set.
      Use addprop and rmprop to modify CustomProperties.

As I've told you already, read the documentation, in particular Access data in tables.

As explained on that page, () indexing returns a table. You want the content of the table which you can access with

daily_stk{:, 2}

or

daily_stk.(2)

or better

daily_stk.mm

so,

rowindex = find(diff(daily_stk.mm) ~= 0)
