matlab中傅里叶逆变换出错 求助高手
程序如下：
>> syms w
>> H=sin(w*2)/w/pi
H =
sin(2*w)/(pi*w)
>> h=ifourier(H)
h =
transform::fourier((cos(w)*sin(w))/w, w, x)/pi^2
>> subplot(1,2,1)
>> ezplot(H)
>> subplot(1,2,2)
>> ezplot(h)
? Error using ==> char
Cell elements must be character arrays.
Error in ==> ezplot at 158
fmsg = char(f);
Error in ==> sym.ezplot at 45
h = ezplot(char(f));
