Given\(L>0\), we need to find an upper bound for\(\left\| f^{(j)}\right\| _{\infty }\)to estimate the series truncation error by Inequality (3.4). It follows by the inverse Fourier transform and Eq. (2.3) that $$\begin{aligned} \Vert f^{(j)}\Vert _{\infty }\le \frac...

In this paper we take a closer look at the analysis approach, better define it as a generative model for signals, and contrast it with the synthesis one. This work proposes effective pursuit methods that aim to solve inverse problems regularized with the analysis-model prior, accompanied by a...
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, ...
Show that the divergence of an inverse square force is zero. Use the divergence theorem to find the outward flux of the vector field F(x, y, z) = 4x^2 i + 5y^2 j + z^2 k across the boundary of the rectangular prism How do yo...
