Hello all,
I am getting to use numerical integration within the trapezoidal rule.
I already have the python function and would like to converting it to a QlikView macro.
The python function:
def trapz(f,a,b,N=20):
x=np.linspace(a,b,N+1)
y=f(x)
y_r=y[1:]
y_l=y[:-1]
dx=(b-a)/N
result=(dx/2)*np.sum(y_r+y_l)
return result
As an example for input parameters: f(x)=exp(x)*x, a=0.1, b=0.8, N=20
Can anyone help me?
Many thanks in advance
