如何将公式转换成字符串显示在axes上
=zpk(z,p,k)所生成式子中z,p,k三个量是用户给定的,
那么它生成的式子就是不能
确定是哪个具体式子,所以如何
正确的将其显示在axes中.就是说
怎样将生成的zpk式子输出(在GUI中)
我的程序如下:
function varargout = cdhsbdszpk(varargin)
% CDHSBDSZPK M-file for cdhsbdszpk.fig
% CDHSBDSZPK, by itself, creates a new CDHSBDSZPK or raises the existing
% singleton*.
%
% H = CDHSBDSZPK returns the handle to a new CDHSBDSZPK or the handle to
% the existing singleton*.
%
% CDHSBDSZPK('CALLBACK',hObject,eventData,handles,...) calls the local
% function named CALLBACK in CDHSBDSZPK.M with the given input arguments.
%
% CDHSBDSZPK('Property','Value',...) creates a new CDHSBDSZPK or raises the
% existing singleton*.Starting from the left, property value pairs are
% applied to the GUI before cdhsbdszpk_OpeningFunction gets called.An
% unrecognized property name or invalid value makes property application
% stop.All inputs are passed to cdhsbdszpk_OpeningFcn via varargin.
%
% *See GUI Options on GUIDE's Tools menu.Choose "GUI allows only one
% instance to run (singleton)".

用哪个参数可以将zpk 生成的式子转换成字符串.

=zpk(z,p,k)所生成式子中
z,p,k三个量是用户给定的,
那么它生成的式子就是不能
确定是哪个具体式子,所以如何
正确的将其显示在axes中.就是说
怎样将生成的zpk式子输出(在GUI中)
我的程序如下:
function varar ... 看不懂，请简明扼要地描述你的问题。你直接说想把什么转换成字符串吧，“zpk生成的式子”让人摸不着头脑 char()clear
clc
syms t
f=t^2*exp(-2*t)*sin(t+pi);
fl=laplace(f)
ezplot(fl);
ylabel(char(fl))
问题解释
我是想问g=zpk(Z,P,K)如何把g 显示在axes上,要求就是说Z,P,K是变量(用户决定的),点了按钮直接就在axes上显示出g 的式子.我先试试上边sogooda的方法谢谢~
sogooda的方法没搞懂啊,还是非常感谢.
要把g=ZPK(Z,P,K)这个公式显示在axes上,char()
不能把整个ZPK函数生成的式子转换成字符串,
