已知 ,计算函数在点(0,1),(2,5),(7,2),(2,4)处的函数值的程序代码是:
A.
clear syms x y f(x,y)=2*x+3*y^2 x=[0,2,7,2];y=[1,5,2,4]; z=f(x,y)
B.
clear syms x y f(x,y)=2*x+3*y.^2 x=[0,2,7,2];y=[1,5,2,4]; z=f(x,y)
C.
clear syms x,y f(x,y)=2*x+3*y.^2 x=[0,2,7,2];y=[1,5,2,4]; z=f(x,y)
D.
clear syms x y f(x,y)=2*x+3*y^2 z=f([0,2,7,2],[1,5,2,4])
