syms t;
syms s;
f=s^0.9*(t-s)^(-0.1);
int(f,s,0,t)
上面是程序。
s^0.9*(t-s)^(-0.1)在[0,t]上对s积分。
高数的书上有结果,但是matlab积不出来。
提示:Warning: Explicit integral could not be found.
ans =
piecewise([t = 1, (5*gamma(9/10)^2)/(8*gamma(4/5))], [Otherwise,
int(s^(9/10)/(t - s)^(1/10), s = 0..t)])
syms s;
f=s^0.9*(t-s)^(-0.1);
