下列程序可否：
一.
syms N k
f=2.6*sqrt(3+2*cos(3.14*N*(6+8)/459.9216-(sqrt(3)/2)*(6/(2.46*sqrt(76)))*k*2.46)+2*cos(3.14*N*(12+4)/459.9216+(sqrt(3)/2)*(4/(2.46*sqrt(76)))*k*2.46)+2*cos(3.14*N*(2/459.9216)+(sqrt(3)/2)*(10/(2.46*sqrt(76)))*k*2.46));
f1=subs(f,N,[0:51]);
f2=vpa(f1,5);
for i=1:length(f2);
figure
ezplot(f2(i))
end
%k不去范围
二.
syms N k
f=2.6*sqrt(3+2*cos(3.14*N*(6+8)/459.9216-(sqrt(3)/2)*(6/(2.46*sqrt(76)))*k*2.46)+...
2*cos(3.14*N*(12+4)/459.9216+(sqrt(3)/2)*(4/(2.46*sqrt(76)))*k*2.46)+...
2*cos(3.14*N*(2/459.9216)+(sqrt(3)/2)*(10/(2.46*sqrt(76)))*k*2.46));
f1=subs(f,N,[0:51]);
f2=vpa(f1,5);
for i=1:length(f2);
figure
ezplot(f2(i),[0 ,1])
end
希望有帮助！！！
