Abstract

The invention belongs to the technical field of mathematical calculation, and discloses a calculation method and device for function derivation, calculation equipment and a storage medium. The methodcomprises the steps: enabling a calculator to obtain function information corresponding to a to-be-calculated function expression input by a user; extracting a target variable type contained in the function information, and determining a target equation type corresponding to the to-be-calculated functional expression according to the target variable type; searching a corresponding derivation calculation model in a preset model database according to the target equation type; constructing an auxiliary function according to the to-be-calculated functional expression, and searching a partial derivative result corresponding to the auxiliary function in a preset partial derivative database; and substituting the partial derivative result into the derivation calculation model, and obtaining a model output result. By means of the mode, various types of functions can be derived quickly and accurately, and the technical problems that in the prior art, derivation calculation is single in type, time is consumed in calculation, and accuracy is hard to guarantee are solved.

Description

technical field [0001] The invention relates to the technical field of mathematical calculations, in particular to a calculation method, device, calculation equipment and storage medium for derivation of functions. Background technique [0002] With the rapid development of social information technology, the requirements for data signal processing in the fields of communication, computer, and instrument control are getting higher and higher, especially involving the calculation of derivatives of data signals, such as analog-to-digital converters, single analog-to-digital converters Performance is difficult to meet the requirements of high speed and high precision at the same time, so the time-interleaved analog-to-digital converter came into being. The parallel structure of the time-interleaved analog-to-digital converter can greatly increase the sampling rate of the system, but due to the time mismatch, gain mismatch and offset mismatch of each channel, the three mismatches...
