Example 1: Using DLMREAD to read in a file with headers, text, and numeric data % This reads in the file 'sample_file2.txt' and creates a matrix, D, % with the numeric data this command specifies a white space as the % delimiter of the file D = dlmread('sample_file.txt','') ...
CSVREAD用来读分隔符是逗号的文件,是DLMREAD的特殊情况。当读空格和Tab分隔的电子数据表文件时,DLMREAD特别有用。以'sample_file.txt'为例: CODE: Example 1: Using DLMREAD to read in a file with headers, text, and numeric data % This reads in the file 'sample_file2.txt' and creates a matrix,...
2,2) the f(x)-value is 79. I am trying to read this into Matlab so I have for a vector (or using repmat a meshgrid-like matrix) for x and one for y. I will not need z since it will not change over the process. Also I want to read in the f(x)-value so I...

In addition to importing numeric tabular data from a text file as a table using readtable, you can also import this data as a matrix into the MATLAB workspace.

thanks for comment. I need to read the whole txt file in a matrix. I presented the first line as a sample. each cell data is separated using semicolon as mentioned. in this case third and forth are date and time of day and all the rest can be saved as double in a matrix. ...
