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, ...
function output = readTestFile(filename) fid = fopen(filename, 'r'); % Read the first line line = ''; while isempty(line) line = fgetl(fid); end nums = textscan(line, '%d %d', 'CollectOutput', 1); a = nums{1}(1); b = nums{1}(2); % Read 'b' of ...
Example 2: Using STRREAD to read the words in a line % This command uses the cell array created in Example 1 to % read in each word of line 28 in 'file' to a cell array, words words = strread(file{28},'%s','delimiter','') CODE: Example 3: Using TEXTREAD to read in text an...

source: the file to be read. May be a file path or just the file name. OR: The text itself, see 'textsource', below. delimiter: (default: ',') any non-empty string. May be a regexp, but this is slow on large files.
