本人要画一个曲线，程序如下：(p为19维行向量，q为19维列向量）
p=[0.19
0.78
0.96
1.31
2.78
3.16
4.15
4.67
4.85
6.5
7.35
8.01
8.27
12.0
13.95
16.0
21.21
27.11
34.95]';
q=[-1.660731207
-0.248461359
-0.040821995
0.270027137
1.022450928
1.150572028
1.423108334
1.541159072
1.578978705
1.871802177
1.994700313
2.080690761
2.112634509
2.48490665
2.635479508
2.772588722
3.054472769
3.299902664
3.553918469];
fplot('[(p.^x)*q/sum(p.^x)-1/x-sum(q)/19,0]',[0.9,1])
运行后显示
??? Error using ==> inline.feval
Not enough inputs to inline function.
Error in ==> fplot at 102
x = xmin; y = feval(fun,x,args{4:end});
请高人指教~Thanks！
