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, ...
csvwrite(filename,M) writes matrix M to file filename as comma-separated values. example csvwrite(filename,M,row,col) writes matrix M to file filename starting at the specified row and column offset. The row and column arguments are zero based, so that row=0 and col=0 specify the...
