将压缩感知用于谱估计中，根据论文谱压缩感知的一些程序(Compressive sensing (CS) is a new approach to simultaneous sensing and compression of sparse and compressible signals based on randomized dimensionality reduction. To recover a signal from its compressive measurements, standard CS algorithms seek the sparsest signal in some discrete basis or frame that agrees with the measurements. A great many applications feature smooth or modulated signals that are frequency sparse and can be modeled as a superposition of a small number of sinusoids. Unfortunately, such signals are only sparse in the discrete Fourier transform (DFT) domain when the sinusoid frequencies live precisely at the center of the DFT bins. When this is not the case, CS recovery performance degrades significantly. In this paper, we introduce a suite of spectral CS (SCS) recovery algorithms for arbitrary frequency sparse signals. The key ingredients are an over-sampled DFT frame, a signal model that inhibits closely spaced sinusoids, and classical sinusoid parameter e)

用matlab编写了20几个常见的技术指标，方便大家开发策略时候，直接调用。 1）编写这些函数不是技术活，完全是体力活 2）之所以编写这些函数，一来是自己研究所需，二来自己编写过程中能够感悟到蕴含在公式中的思想 3）几乎所有函数，我都用数据测试过，并和交易开拓者、同花顺等计算的值进行了比对，最大程度 上保证指标算法的准确性。虽然已近极力避免错误，但是还是可能出现一些这样那样的错误，所以 请批判性使用这些函数 4）如果对这些函数有疑问（比如有些指标可能会有不同的处理方法），请参见函数中的参考文献部分 5）如果您的策略用到了这些函数，请一定研究这些函数的编写过程，避免未来函数、偷价漏价对你造成的干扰。(20 using matlab few common technical indicators, to facilitate the development of strategies when called directly. 1) preparation of these functions are not technology live, is completely manual labor 2 thoughts) reason to write these functions, one is required for their own research, and secondly to be able to comprehend the process of writing their own inherent in the formula 3) Almost all of the functions that I have tested with the data, and the Trail Blazers and trading, such as flush with the calculated values were compared right, the greatest degree of     On indicators to ensure the accuracy of the algorithm.
