matlab中 Error using ==> plot Conversion to double from sym is not possible.的问题
clear all
clc
syms t gamma r1 i a
%
t=0:pi/50:pi/2;
gamma=0:pi/50:pi/2;
r1=3;
i=4;
a=r1+r1*i;
plot(x1,y1,'g',x2,y2,'r',x,y,'k');
axis equal
我想画出(x1,y1),(x2,y2)和(x,y)的曲线,可是出现Error using ==> plot
Conversion to double from sym is not possible.的问题
请问各位如何解决?
谢谢了!

plot函数要求输入宗量是数值类型,sym符号类型是不行的.把开头定义符号变量的语句去掉.
