Minimize a differentiable multivariate function，函数接口说明：[X, fX, i] = minimize(X, f, length, P1, P2, P3, ... )tvreg：全变差正则化图像处理（Pascal Getreuer )
The tvreg package applies total variation (TV) regularization to perform image denoising, deconvolution, and inpainting. Three different noise models are supported: Gaussian (L2), Laplace (L1), and Poisson.
