table
A , Datetime,
2 05/20/22
2 05/20/23
3 04/12/99
3 06/12/02
the goal is to have two more columns with min and max dates
table
A , Datetime, Min, Max
2 05/2/22 05/2/22 05/2/23
2 05/2/23 05/2/22 05/2/23
3 04/12/01 04/12/01 06/12/02
3 06/12/02 04/12/01 06/12/02
I was tring table_min = groupsummary (table,{table.A,table.Datetime}, 'min'}
table_max= groupsummary (table,{table.A,table.Datetime}, 'max'}
So I join this date to table but i'm getting an error :
[groupingData,groupVars] = matlab.internal.math.parseGroupVars(groupVars,tableFlag,'groupsummary',T);
Thank you.

T = table( ...
[2;2;3;3], ...
datetime({'05/20/22';'05/20/23';'04/12/99';'06/12/02'},'InputFormat','MM/dd/yy'), ...
'VariableNames',{'A' 'Datetime'})
table_min = groupsummary (T, 'A', 'min')
table_max = groupsummary (T, 'A', 'max')
g = findgroups(T.A)
T.Min = table_min{g,'min_Datetime'};
T.Max = table_max{g,'max_Datetime'};
T
