说明：  通过采用matlab编程，用有限差分法来确定温度(By using matlab programming, finite difference method to determine the temperature)

pitch=CorrelogramPitch(correlogram, width [, sr, lowPitch, highPitch]) computes the pitch of a correlogram sequence by finding the time lag with the largest correlation energy. (pitch = CorrelogramPitch (correlogram. width [02:04 lowPitch. highPitch]) computes the pitch of a correlogra m sequence by finding the time lag with the large st correlation energy.)

一种适用于图像的压缩感知采样策略和重建算法，采样策略是基于块的图像稀疏采样矩阵，重建算法为smoothed projected Landweber（SPL）迭代算法。(BCS-SPL combines block-based compressed-sensing sampling (BCS) of an image with a smoothed projected-Landweber (SPL) iterative reconstruction. Sampling is driven by random matrices applied on a block-by-block basis, while the reconstruction is a variant of projected Landweber (PL) reconstruction (also known as iterative hard thresholding (IHT)) that incorporates a smoothing operation (Wiener filtering) intended to reducing blocking artifacts. In essence, this filtering operation imposes smoothness in addition to the sparsity inherent to PL.)
