MATLAB 保存文件

clc;clear;close
B=zeros(100,100)*1/0;
row=10;
num=[];
for i=1:row
    A=[];
    A = 1:2:2*i;
    num=[num length(A)];
    B(i,1:length(A))=A;
end
column=max(num);
C=B(1:row,1:column)
save('test_C.txt','C','-ascii')
a=1:10;

b=1:20;

num=[];

num=[num length(a)];

num=[num length(b)]; %依次类推

m=length(num);

n=max(num);

c=zeros(m,n)*1/0; %用无穷bai大填充NaN

%c=zeros(m,n); %用零填du充

c(1,1:num(1))=a;

c(2,1:num(2))=b;

c
%p(3,~isnan(p(3,:))) %读取质数

 上面为保存不同长度的数列到矩阵中，并保存到TXT文件当中

 将字符串和数值型矩阵，输出txt文件，方便arcgis读取

clc
clear
close all
title = {'name'，};
txt = [1 2];
txt = txt'
fid = fopen('my_try_save_txt.txt','wt');% 'wt'，加入‘t’方便换行输出

a = title(1);

a = cell2mat(a);

fprintf(fid,'%s %s %s\n',a);

fprintf(fid,'\n%g %g %g',txt);

fclose(fid)

 

%my additional function m path
addpath('D:\Matlab_my_additional_path\')
% add additional data path

addpath(genpath('D:\UCRArchive_2018'))
files = readcell('file_list.txt');
%main read name loop

for ci = 1:numel(files)

data = load([char(files(ci)),'_TRAIN','.tsv'])
