启动matalb后，输入pwd，查看当前路径。直接改掉起始位置即可。

C:\Users\Administrator\Documents\MATLAB E:\software\MATLAB\R2017b\toolbox\matlab\datafun E:\software\MATLAB\R2017b\toolbox\matlab\datatypes E:\software\MATLAB\R2017b\toolbox\matlab\elfun E:\software\MATLAB\R2017b\toolbox\matlab\elmat E:\software\MATLA

locs_valid=[locs(3:end)];

不是./也不是.\如果只写文件名信息，matlab就会认为是当前路径fid=fopen('locs.txt','w');% fprintf(fid,'%7s %9s\r\n','Radius','Area');%写入列名fprintf(fid,'%8d\r\n',locs);%写入每列的数据fclose(fid);

花括号{}的数据类型是cellnumlist={3,6,18}for k1 = 1:length(numlist) fprintf('Number at position %d = %6.2f\n', k1, numlist{k1})end中括号[]的数据类型是arrayv=[1,4,6,4,1];s=0;for i=1:length(v) s=s+v(i);enddisp(s);...

下面两种方法计算结果是一致的。matlab 计算结果 ​f=(x^2+2*x+1)*(2*x^2+x+3) collect(f,x)​ 2*x^4 + 5*x^3 + 7*x^2 + 7*x + 3 conv([1,2,1],[2,1,3]) 2 5 7 7 3

linux下面matlab添加新的工具箱(还没弄完)

代码如下:X=0:0.1:1;Y=[-0.447 1.978 3.28 6.16 7.08 7.34 7.66 9.56 9.48 9.30 11.2];C=polyfit(X,Y,2);Z=polyval(C,X);plot(X,Y,'+',X,Z,'b');%n=2阶显示拟合结果hold onD=polyfit(X,Y,4);M=polyval(D,X);plot(X,M,'r')%n=4阶进行拟合的曲线结果hold onD=polyfit(X,Y,10);M=polyv

z=[20,0.0556,50,0.2609,100,0.2258,150,0.25,200,0.2366,250,0.2574,300,0.2464,350,0.2485,400,0.2413]x=z(1:2:end-1)y=z(2:2:end)plot(x,y,'-+')效果如下 :

读取文件:%采样获得的数据data=importdata('/home/appleyuchi/桌面/心电信号处理算法设计/任务/data4.txt');M=data';TIME=linspace(0,18.68,1868);%时间写入文件:close all; clear all; clc;r=1:1:10;results=[r;pi*r.^2];fid=fopen('radiusandarea.txt','w');fprintf(fid,'%7s %9s\r\n',

首先选择HOME，然后选择Preference选择keyboard->Shortcuts然后把copy paste和undo分别搜索分别改掉就行了

Ubuntu20.04下面的Matlab2015b在matlab中输入下列命令来获取色彩配置文件的路径>> prefdirans =/home/appleyuchi/.matlab/R2015b所以目标修改文件就是:/home/appleyuchi/.matlab/R2015b/matlab.prf--------------------------------------------------------------------------------..

代码如下:syms x yf=x*y*sin(x+y);dfx=diff(f,x)dfx =y*sin(x + y) + x*y*cos(x + y)
