我要解一个方程:10.*t.*exp(-10*t)+exp(-10*t)-0.9=0,我用PLOT函数画了此图象,值在0-1之间,然后用fzero
求方程:fzero('10.*t.*exp(-10*t)+exp(-10*t)-0.9',[0 1]),之后便跳出错误:
??? Error using ==> fzero
FZERO cannot continue because user supplied expression ==> 10.*t.*exp(-10*t)+exp(-10*t)-0.9
failed with the error below.
Error using ==> inlineeval
Error in inline expression ==> 10.*t.*exp(-10*t)+exp(-10*t)-0.9
??? Error using ==> eval
Undefined function or variable 't'.
请问这个是什么错误啊??
