除了應用樣條函數插值方法外,解決數值逼近問題還可以採用小波分析中多尺度分析的方法。In order to calculate easily and do n ' t influence the single - chip microcomputer ' s calculate velocity, we put forward two scheme to deal with the numerical value, one is to use a simple function to close or approach a normal function f ( x ) ( mainly is lagrange ' s intepolation, newton ' s intepolation, hermite ' s intepolation, cubic spline interpolation, etc. ) the other one is function approach ( mainly is chebyshev ' s polynomic. legendre ' s polynomic, laguerre ' s polynomic, method of least squares, etc. ), we analyze and compare the lagrange ' s intepolation and chebyshev ploynomic, at last, we select the chebyshev polynomic to do the value calculating on single - chip microcomputer
提出了數值處理的二種方案。即用簡單函數近似或逼近一個一般函數f ( x ) (主要有拉格朗日插值、牛頓插值、埃爾米特插值、三次樣條插值等)和函數逼近(主要有切比雪夫多項式、勒讓德多項式、拉蓋爾多項式、最小二乘法等) ,對上述兩個方案中的典型函數?拉格朗日插值和切比雪夫多項式進行了分析比較,最後選取切比雪夫多項式完成單片機上的數值計算。In this paper, systemic theoretic analysis of the relationship of stock structure and operating performance is progressed, based on this, theoretic study and demonstration analysis organic fall together, and the neural networks model that can reflect their relationship total and systemic is established. the input variable of the model can reflect the panorama of stock structure, also, it can embodiment other influence factor of company performance. the evaluation target system that can reflect the operating condition of listed companies completely, impersonality and truly is advanced, at the same time, the best result weights confirm method is brought forward, thereby, the fuzzy integrate evaluations method is improved
本文對股權結構與經營績效之間的關系作了系統的理論分析,並在此基礎上,將理論研究和實證分析有機地結合起來,建立了一個能全面、系統地反映它們之間關系的神經網路模型:該模型的輸入變量在反映股權結構全貌的同時又體現了公司績效的其它影響因素;提出了可以全面、客觀、真實地反映上市公司經營狀況的評價指標體系,同時提出了最佳結果權重確定法,從而改進了模糊綜合評價方法,並利用改進的模糊綜合評價法求出公司經營績效的綜合量化值作為神經網路的期望輸出;改進了神經網路模型的演算法,使其在樣本數據相對較少的條件下也能很好地在性態上模擬被逼近函數。Cubic spline functions polynomial are used directly to approximate the time - varying coefficients
利用三次樣條基函數多項式逼近時變系數,將時變參數的佑計轉化為定常參數的估計。Firstly, in the reproducing kernel space, the spline function is discussed and its equivalent relations are gived ; we prove that the 2 - th differential operator interpolation spline function in the space can be expressed not only by the reproducing kernels but also by polygonal functions. so it is easy to prove its best approximation properties in theory and is convenient for numerical calculation in applications, too
首先,在再生核空間中討論樣條函數,給出其等價性條件;證明了空間中的一個二階微分運算元插值樣條既可由再生核函數表示又可由折線函數表示,這不僅在理論上便於獲得此種插值樣條函數的最佳逼近性質,而且在應用上也便於數值計算。With the structure character of coiling robot, the transformed equations of robot movement is established by using equal - power coordinate transformation. the path scheduling method of robot is deeply researched and then imitates the robot ' s movement path by using b - splint function on the disperse point gotten by scheduling on robot ' s coiling movement path to ensure the robot ' s movement track to be a clean and continuous line. then the track is optimized by dynamic scheduling method
結合繞線機器人的結構特點,利用齊次坐標變換建立起機器人運動變換方程,探討了機器人路徑規劃的一般方法,並利用b樣條函數對機器人繞線運動路徑規劃所得的離散路徑點進行逼近,以保證機器人運動軌跡是一條光滑連續的曲線,並利用動態規劃方法對機器人進行時間最優軌跡規劃。The analysis is relatively simple due to the good approximation and the compact expression of the spline function
由於樣條函數有良好的逼近性及緊湊性,使得層合板在脈動流這種復雜荷載作用下的動力分析也相對簡單。This paper is devoted to nonlinear approximation, namely, m - term approximtion of anisotropic smooth periodic functions. nonlinear approximation is the important part of approximation the - ory. it means that the approximants do not come from linear spaces but rather from nonlinear manifolds. the advantages of nonlinear approximation show that one can achieve a given accuracy of approximation while assuming less smoothness on the function in the nonlinear case than is necessary in the corresponding linear approximation. nonlinear approximation is used significantly in many applications, such as image processing, noise removal and the solution of operation equations and so on
非線性逼近與線性逼近最大的區別在於所用的逼近子空間不是固定的,而是依賴于被逼近的函數其主要優點是對光滑度較低的函數仍可以得到較高的估計階。隨著小波和樣條的廣泛使用非線性( m項)逼近成為較熱門的話題,它在圖象處理,聲的傳播,運算元方程的求解等方面都有很多應用。The last part of this paper treated the results with the assistance of spline function and nth - degree harmonics cam approximate. thus, the new function of tappet, speed and accelerated speed was gained and the whole designing process was completed
