Description: MACD指标(Moving Average Convergence Divergence) 平滑异同移动平均线. 主要是利用长期与中短期移动平均线来计算两者之间的差离情况，作为研判未来行情走势的依据，其中包括了三条线：MACD线、DIF线（是核心）、柱状线 BAR（MACD辅助指标—用红柱和绿柱，其公式为：BAR=2×(DIF－DEA)）。但要切记：任何指标相对于成交量而言都是滞后的，避免进入纯指标分析误区， 所以任何技术指标不能孤立的使用。-MACD indicator (Moving Average Convergence Divergence) moving average smoothing differences and similarities. Mainly used in long-term and short-term moving average calculated from the difference between the two cases, as judged based on future market trends, including the three lines: MACD line, DIF line (the core), columnar lines BAR (MACD auxiliary indicators- with红柱and the Green column, the formula is: BAR = 2 × (DIF-DEA)). However, bear in mind: in relation to any indicators are lagging behind in terms of volume to avoid errors into the net index analysis, it can not be any technical indicators for the use of isolation.

Description: function [x, hist] = secant(x, f, tola, tolr)
SECANT This a secant code with no line search.
This code terminates on small relative-absolute errors function [X, HIST] = SECANT(X, F, TOLA, TOLR) Inputs: X = initial iterate
F = function
TOLA = absolute error tolerance
TOLR = relative error tolerance
Output: X = approximate result-function [x, hist] = secant(x, f, tola, tolr)

Description: DFIELD6 is an interactive tool for studying single first order differential equations. When DFIELD6 is executed, a DFIELD6 Setup window is opened. The user may enter the differential equation and specify a display window using the interactive controls in the Setup window. When the Proceed button is pressed on the Setup window, the DF Display window is opened. At first this window displays a direction line field for the differential equation. When the mouse button is depressed in the DFIELD6 Display window, the solution to the differential equation with that initial condition is calculated and plotted. Oher options are available in the Options menu. These are fairly self explanatory. The Settings option allows the user to change several parameters. Included here are the possibilities of using a vector field instead of the default line field, and of changing the number of field points computed and displayed.-DFIELD6 is an interactive tool for studying single first order differential equations.
