AssociationComap
AssociationComap[{key1,key2,…},x]
creates the association key1key1[x],key2key2[x],…>.
AssociationComap[keys]
represents an operator form of AssociationComap that can be applied to an expression.
Details
- AssociationComap is typically used to apply each of a list of functions to a single common argument, creating an association of the corresponding values.
- If AssociationComap produces repeated keys, later instances replace earlier ones. »
- AssociationComap uses the keys as heads to produce the values. AssociationMap uses the keys as arguments. »
- AssociationComap[keys][x] is equivalent to AssociationComap[keys,x].
- Parallelize[AssociationComap[{key1,key2,…},x]] computes AssociationComap[{key1,keys2,…},x] in parallel on all subkernels. »

Create an association by wrapping an expression with each element in a list of keys:
AssociationComap[{f, g, h}, x]Use the operator form of AssociationComap:

AssociationComap[{f1,f2,…},x] creates an association with keys fi:
AssociationComap[{f, g, h}, x]Keys[%]The values in the association are given by Comap[{f1,f2,…},x]:
Values[%%]% === Comap[{f, g, h}, x]AssociationComap[{f1,f2,…},x] is equivalent to AssociationThread[{f1,f2,…}Comap[{f1,f2,…},x]]:
AssociationComap[{f, g, h}, x]Comap[{f, g, h}, x]%% === AssociationThread[{f, g, h} -> %]AssociationComap[list,x] gives an association with the same length as DeleteDuplicates[list]:
list = {f, g, g};AssociationComap[list, x]Length[%] == Length[DeleteDuplicates[list]]AssociationComap wraps the keys in a list around an expression:
AssociationComap[{f, g, h}, x]AssociationMap wraps an expression around the keys in a list:
