When I usereadtable, Matlab format the csv header content, which is not helpful. It also skips the second header line (subtitle X_Y). Then I found readmatrix, but I also can not import the file with it as expec
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, ...
filename = fullfile(filepath,"smartflux.csv"); opts = detectImportOptions(filename,'NumHeaderLines',3);% number of header lines which are to be ignored opts.VariableNamesLine = 2;% row number which has variable names opts.DataLine = 4;% row number from which the actual data starts ...

Skip header rows or columns by specifying row and column offsets. All values in the file other than headers must be numeric. Algorithms csvreadfills empty delimited fields with zero. When thecsvreadfunction reads data files with lines that end with a nonspace delimiter, such as a semicolon,...
IMPORTDATA形成UIIMPORT的功能,不打开GUI。可以将IMPORTDATA用于函数或者脚本中,因为在函数或者脚本中基于GUI的文件导入机制并不理想。下面的例子用到包含几行文件头和文本、数值数据的文件'sample_file2.txt': This is a file header. This is file is an example. ...
Read the file, converting empty cells to -Inf. Get filename = 'data.csv'; fileID = fopen(filename); C = textscan(fileID,'%f %f %f %f %u8 %f',... 'Delimiter',',','EmptyValue',-Inf); fclose(fileID); column4 = C{4}, column5 = C{5} column4 = 2×1 4 -Inf column...
