What does the confusion_matrix line of code do?

from sklearn.pipeline import Pipeline
model = Pipeline([('vectorizer',tvec),('classifier',clf2)])
model.fit(IV_train, DV_train)
from sklearn.metrics import confusion_matrix
predictions = model.predict(IV_test)
confusion_matrix(predictions, DV_test)

I want to know what the confusion matrix line in the code does.
