ylabel.m

这是MATLAB小型的。下下去看看嘛

function hh = ylabel(string,varargin)
%YLABEL Y-axis label.
%   YLABEL('text') adds text beside the Y-axis on the current axis.
%
%   YLABEL('text','Property1',PropertyValue1,'Property2',PropertyValue2,...)
%   sets the values of the specified properties of the ylabel.
%
%   H = YLABEL(...) returns the handle to the text object used as the label.
%
%   See also XLABEL, ZLABEL, TITLE, TEXT.
