MATLAB 函数Semilogy() _MATLAB函数

它使用x的线性标度和y的对数标度来生成x和y值的图。
句法

semilogy(Y) // It generates a plot using a base 10 logarithmic scales for the y-axis and linear scales for the x-axis. It plots the column of Y versus their index.semilogy(X1, Y1, ...)//It plots all Yn versus Xn pairs.semilogy(X1, Y1, LineSpec, ...)// It plots all the lines described by the Xn, Yn, LineSpec triples. LineSpec determine line style, marker symbol, and color of the plotted lines.semilogy(..., 'PropertyName', PropertyValue, ...)//It sets property values for all the charting lines created by semilogy. semilogy(ax, ...)//It generates the line in the axes specified by ax instead of in the current axes (gca). The option ax precedes any of the input argument combinations in the previous syntaxes.h = semilogy(...)//It returns a vector of chart line objects.
