Setdiff usage in matlab

Setdiff usage in matlab

Help document content:

SETDIFF (A, B) when A and B are vectors returns the values
In A that are not in B. The result will be sorted. A and B
Can be cell arrays of strings.
 
SETDIFF (A, B, 'rows ') when A are B are matrices with the same
Number of columns returns the rows from A that are not in B.

Understanding:

Setdiff () function in matlab: used to determine different elements in two Arrays

C = setdiff (A, B)
Returns the values in A, but not in B. The result vector is returned in ascending order. In set theory, c = A-B. A and B can also be string cell arrays.
C = setdiff (A, B, 'rows ')

When A and B are matrices with the same number of columns, the rows in A but not in B are returned.
