Misol
y = 2xsin x va z = 3x² + cos x funksiya qiymatlarini x[–1,5; 1,5] oraliqda 0,5 qadam bilan hisoblang.
Kiritish tartibi:
>> x=–1.5:0.5:1.5
>> y=2*x.*sin(x)
>> z=3*x.^2+cos(x)
Quyidagi natijani olamiz:
x=–1.5000 –1.0000 –0.5000 0 0.5000 1.0000 1.5000
y= 2.9925 1.6829 0.4794 0 0.4794 1.6829 2.9925
z= 6.8207 3.5403 1.6276 1.0000 1.6276 3.5403 6.8207
