في هذا البحث نقوم بدراسة قابلية جمع متسلسلة فورييه ( و تدعى معاملات فورييه ), و ذلك بالطريقة المصفوفية.
سيتم عرض هذه الطريقة من خلال مبرهنة مع إثباتها, و لكن بعد وضع التعاريف
و المفاهيم الأساسية اللازمة لذلك.

تعد متسلسلات فورييه المثلثية إحدى الدراسات الهامة في التحليل الحديث وقد برزت هذه المتسلسلات لاول مرة عند دراسة العالم برنوبي للأوتار المهتزة عام (1753)
