v=setdiff(a,b)

[v,ka]=setdiff(a,b)

Parameters

• a : vector of real numbers or strings
• b : vector of real numbers or strings
• v : vector of real numbers or strings with same orientation than a
• ka : row vector of integers, ka(i) is the location of v(i) in a

Description

setdiff(a,b) returns a sorted vector which retains the a entries which are not in b

[v,ka]=setdiff(a,b) returns a sorted vector which retains the a entries which are not in b and the location of these entries in a.
