nodes and weights Parameters --- n : int number of nodes a : float left endpoint b : float right endpoint Returns --- x : array, shape (n,) nodes x : array, shape (n,) weights Notes --- Port of the qnwcheb1 function in the compecon matlab toolbox. """ x = ((b + a)...
for many financial models, the densityfof the log-returns is unknown. Fortunately, the characteristic function of the log-returns is often given in closed form and can be used to obtain the density.
The unit step function is also named the Heaviside step function was coined by physicist Oliver Heaviside. The Unit step function provides an output for positive values and remains zero for negative values. The unit step function is represented mathematically as, ...
Evaluate the triple integral, triple integral_E z dv, where E is the region bounded by the cylinder y^2 + z^2 = 9 and the planes x = 0, y = 0, y = 3 x, and z = 0 in the first octant. How can you determine gain and ph...
