Scilab Function integrate - integration by quadrature
Calling Sequence
- [x]=integrate(expr,v,x0,x1 [,ea [,er]])
Parameters
- expr
: external Scilab
- v
: string (integration variable)
- x0,x1
: real numbers (bounds of integration)
- ea,er
: real numbers (absolute error bound) Default value: 0
- er
: real number, (relative error bound) Default value: 1.d-8
Description
computes :
The evaluation hopefully satisfies following claim for accuracy:
abs(I-x)<= max(ea,er*abs(I)) where I stands for the
exact value of the integral.
Examples
integrate('sin(x)','x',0,%pi)
integrate(['if x==0 then 1,';
'else sin(x)/x,end'],'x',0,%pi)
