Approksimatsiyalash xatoligi:
H I S O B ( C a l c u l u s )
22
Funksiyalarni approksimatsiyalash
va egri chiziq yasash uchun dasturiy
paketlar
MATLAB
MathCad
Excel
Maple
Ushbu mavzuda funksiya
ko’rinishini tiklashni o’rgandik.
Keyingi 7-mavzuda funksiya grafigini chizishni
o’rganamiz.
H I S O B ( C a l c u l u s )
23
Mavzuni mustahkamlash uchun savоllar
1. Approksimatsiyalash deb nimaga aytiladi?
2.
Interpolyatsiyalash turlarini sanab bering.
3.
Chiziqli interpolyatsiya nima?
4. Kvadratik interpolyatsiya formulasi qanday hosil qilinadi?
5. Lagranj interpolyatsion formulasi qanday va uning afzalligi nimada?
6. Lagranj ko’phadini yozing.
