How do I use the group summary/unstack function in this script?

Question

This is my script:

date1 = datetime(2020,10,12,'Format','yyyy/MM/dd');

date2 = datetime(2020,10,15,'Format','yyyy/MM/dd');

Date = [date1;date1;date1;date2];

Concept = ["Petrol";"Woolworths";"ALDI";"Opal Card"]; T

ype = ["Credit";"Savings";"Cash";"Credit"];

Category = ["Car";"Groceries";"Groceries";"Transportation"]

; Amount = [55;63;15;20];

T = table(Date,Concept,Type,Category,Amount)

It looks like this

I am trying to create another table to reflect these results:

I tried using groupsummary function but it would only allow me to use the variables of the columns and not the two dates I need.

Is anyone able to point me in the right direction?

Take a look at the following documentation example for unstack, which closely resembles your problem.
