Help Center Help Center. Groups are defined by rows in the variables in groupvars that have the same unique combination of values. Each row of the output table corresponds to one group. For more information, see Group Counts Computation. Groups are defined by rows in the column vectors in A that have the same unique combination of values. Each row of B contains the count for one group. BG is the unique grouping vector combinations corresponding to the rows in B. BP is the percentage of the data each group count in B represents. The percentages are in the range [0, ]. Group the individuals by health status, and return the number of and percentage of individuals in each group. Group the individuals by health status and smoker status, and return the number of and percentage of individuals in each group. By default, groupcounts suppresses groups with zero elements, so some unique combinations of the grouping variable values are not returned. To return a row for each group, including those with zero elements, specify IncludeEmptyGroups as true. Compute the group counts by the total items sold, binning the groups into intervals of item numbers. Determine which elements in the vector appear more than once by creating a logical index for the groups with a count larger than 1.

Search pattern, specified as one of the following: String array Character vector Cell array of character vectors pattern array since Rb. Sort ages into bins with varying ranges between 0 and If binranges contains complex values, then histc ignores the imaginary parts and uses only the real parts. Toggle Main Navigation. BinMethod — Binning algorithm 'auto' default 'scott' 'fd' 'integers' 'sturges' 'sqrt' Bin indices, returned as an array of the same size as X. Search Support Clear Filters. For example, if you have a string array grouping variable such as HealthStatus with elements "Poor" , "Fair" , "Good" , and "Excellent" , you can convert it to a categorical variable using the command categorical HealthStatus. You can specify the number of bins as a positive integer scalar.
