振动信号三分之一倍频程谱，估计随机振动信号的频率谱函数(One-third octave spectra of the vibration signal)

优化 Bitmap的小程序 希望对大家有用我人有很有借鉴意义(Optimize the Bitmap small program hope useful for everyone I have a lot of reference)

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
