definition of f)
t=linspace(.01,1,1e3)'; plot(t,f(t))
If you are doing numerical calculus to understand/study real life
phenomena, you may not need infinite resolution and you can use a
smoothed version of your function. If you want "exact" mathematics you
will need a lot of iterations for your numerical scheme... if the
integral exits...
when i write the first line of above code, it gives me parse error, syntax error
Ok when i run this code, it says"error tolerance not met. estimated error 0.86536. ans=0.112577+0.018141i"
Can i take this answer or it is wrong since error tolerance is not met?
