setdifsa

Purpose

Returns the unique elements in one string vector that are not present in a second string vector.

Format

sy = setdifsa(sv1, sv2)
Parameters:
  • sv1 (Nx1 or 1xN string vector) – data
  • sv2 (Mx1 or 1xM string vector) – data
Returns:

sy (vector) – Lx1 vector containing all unique values that are in sv1 and are not in sv2, sorted in ascending order.

Examples

string sv1 = { "mary", "jane", "linda", "john" };
string sv2 = { "mary", "sally" };

sy = setdifsa(sv1, sv2);

Now sy is equal to:

jane
john
linda

Remarks

Place smaller vector first for fastest operation.

When there are a lot of duplicates it is faster to remove them first with unique() before calling this function.
