Image interpolation methodGaussian-Sinc functionpartition of unity propertyIn this paper,we propose a novel image interpolation method by using Gaussian-Sinc automatic interpolators with partition of unity property.A comprehensive comparison is made with classical image interpolation methods,such as the bicub...
摘要:针对一类奇异摄动过渡层问题,采用具有高精度的Sinc配点法进行离散求解。利用双指数变换,将自然定义在无界区域上的Sinc配点法推广到求解带有齐次Dirichlet边界条件的两点边值问题。对于非齐次Dirichlet边值问题,设计线性函数对未知函数进行改造,将原问题转化为...

also, Sinc function for interpolation points xk=kh is given by S(k,h)(jh)=δkj(0)=1,k=j,0,k≠j. So, S(k,h)∘ϕ(x) exhibits Kronecker delta behavior on the grid points xk=ϕ-1(kh)=a+bekh1+ekh and interpolation and quadrature formulas for f(x) over [a,b] are f(...

Figure 1: Possible multiplexing of sinc-shaped Nyquist pulses. The temporal and spectral features of sinc-shaped pulses bring benefits not only to optical communications but also to many other fields. Actually, sinc-shaped pulses correspond to the ideal interpolation function for the perfect restoratio...
Another technique of Lagrange interpolation polynomials (used as test functions) is not so much useful to determine the oscillating solution or problems with unbounded domains. A desirable use of sinc functions can deal with these adversities while keeping the experimental convergence rate. As the ...

You should therefore implement a more intelligent version of the helper which fits your purposes. You should also be aware that most frameworks already bring their own include helper, e.g. Rails has `render`. ## Text interpolation Use standard Ruby interpolation. The text will be html escaped...
