% 这样用repmat() 操作后赋值给Matrix矩阵, 现在 matlab命令行下的Matrix 是刚新修改的矩阵了, 但是磁盘中的Matrix.txt文本的内容还是没有修改之前的内容 %也就是说matrix.txt中的矩阵还是只有Matrix , 而不是现在用repmat()修改之后的10个Matrix的10行1列的Matrix内容的新的Matrix矩阵 %保存新的Matrix矩阵到磁盘...
打开文件（注意修改文件名）fid = fopen('480684994.txt','rt');if fid == 0, return, end% 读文件直到结束 while ~feof(fid)每次读入一行 s = fgetl(fid);% 以空格作为数据项的分隔符

What kind of matrix are you wanting? Numeric matrices must have the same number of elements in each row. Did you want the missing values to be filled in with NaN or with 0, or did you want to use a cell array?
[Copy to clipboard][ - ] CODE: % Load the file to the matrix, M : M = load('sample_file.txt') % Add 5 to M : M = M +5 % Save M to a .mat file called 'sample_file_plus5.mat': save sample_file_plus5 M % Save M to an ASCII .txt file called 'sample_file_plus5....
1、打开一个txt文件，会发现他既有字符又有数值。2、此时将字符全部删除，只留下有用的数据数值。3、记住该文件夹的地址，一会要作为路径用于matlab读取。4、此时使用一个textread函数，函数内部代入刚才的txt文件路径。5、textread函数会把这些数据读成1为向量。我们将其分为两列，用x和y代表，保存为...
