matlab里ifft之后为什么是nan 10
s=ezf.*sfst=ifft(s)s运行完了还是有结果的:Columns1through5Inf-0.0009+0.0020i0.0034-0.0000i-0.001...
s=ezf.*sf
st=ifft(s)
s运行完了还是有结果的:
Columns 1 through 5
Inf -0.0009 + 0.0020i 0.0034 - 0.0000i -0.0014 - 0.0004i 0.0004 - 0.0026i
Columns 6 through 10
0.0029 0.0004 + 0.0028i -0.0016 + 0.0005i 0.0045 + 0.0000i -Inf - Infi
为什么对它进行ifft之后就变成nan + nani了?
st =
Columns 1 through 5
NaN - Infi NaN + NaNi NaN + NaNi NaN + NaNi NaN + Infi
Columns 6 through 10
Inf + Infi Inf + NaNi NaN + NaNi NaN + NaNi NaN - Infi 展开
st=ifft(s)
