你整个程序中就没有定义h这个变量.

close all close与close all命令的区别! 请教Matlab close ,clear什么用法?请教Matlab close,clear 什么用法?什么时候用这个,看到有的程序里面最开始有的写clc或者clear或close all 或clear all ,不知道到底怎么用才是正确的.比如有的程序开头写 为什么我的程序无图（matlab）clear all;close all;clc;t=-3:0.01:3;x=(abs(t) Close All files Except Active Clear all your comments什么意思 Please confirm all is clear.怎么回答 这些VFP命令怎么发音 用拼音 COPY STRU TO COUN TO INDEX CLEAR DELETE CLOSE ALL SET TALK ON APPE FROM We all like to fell close to Did you close all the windows? The shop____(close)all day on Sunday Close close you all want during a lifetime happiness 求matlab的程序的每句详解clc;clear all;close all;PointNum=100;%一个周期为100个点Interval=2*pi/PointNum;theat=0:Interval:2*pi-Interval; vfp中,close all命令和close tables all命令有何区别? all all all all
