Frequency table


TABLE = tabulate(x)


TABLE = tabulate(x) creates a frequency table of data in vector x. Information in TABLE is arranged as follows:

  • 1st column — The unique values of x

  • 2nd column — The number of instances of each value

  • 3rd column — The percentage of each value

If x is a numeric array, TABLE is a numeric matrix. If the elements of x are nonnegative integers, TABLE includes 0 counts for integers between 1 and max(x) that do not appear in x.

If x is a categorical variable, character array, or cell array of strings, TABLE is a cell array.

tabulate(x) with no output arguments displays the table in the command window.


tabulate([1 2 4 4 3 4])
  Value  Count  Percent
  1      1      16.67%
  2      1      16.67%
  3      1      16.67%
  4      3      50.00%
