controlled decay on [0,∞). Considering a function u(x, t) that can be the represented

u(x<sub>0</sub>, t<sub>N</sub>). A mathematical framework and efficient computational schemes are developed to determine approximate solutions for various classes of partial differential equations via sampled data by first establishing a near-best approximation of&nbsp;<span style="text-align: justify;">ƒ</span><span style="text-align: justify;"></span> .<br/></p>},
