2.2Matlab va WPF texnologiyasi orqali grafik hosil qilsh.

Hozir ko’rsatiladigan dasturda matlab vaWPF texnologiyasini bog’lab natija olingan.

Bu C# WPF dasturiga MATLAB uchastkasini Import qilish
matlab codi
C# code matlab bilan o'zaro bog’langani. Dastur yopilganda matlabni yopish uchun kod ham qo'shamiz.
