while feof(file_id) == 0 % 这就是大名顶顶的fread了,数据类型是int16,每次读入512个数 % raw_array每次都是512x1的矩阵,ele_count为读入的数的个数(正常情况下应为512) [row_array, ele_count] = fread(file_id, 512, 'int16') ; if ele_count < 512 % elecount < 512代表数据不够,已经到...

您无法使用csvread读取文本字符串。 这是另一个解决方案：fid1 = fopen('test.csv','r'); %# open csv file for reading fid2 = fopen('new.csv','w'); %# open new csv file while ~feof(fid1) line = fgets(fid1); %# read line by line A = sscanf(line,'%*[^,],%f,%f'...
I have a text file "param.txt" that stores values like:lon = 120lat = 30...Now I want to read all these parameters (including names and values) in to MATLAB, and save in a structure.Solution:Since the format of param.txt is more or less regular, the best way to do this object...

EXAMPLE 1: [a,b]= readtext('txtfile', '[,\t]', '#', '"', 'numeric-empty2zero') This will load the file 'txtfile' into variable a, treating any of tab or comma as delimiters. Everything from and including # to the next newline will be ignored. Everything between two double...
1、csvread函数的调用格式如下: ● M = csvread('filename'),将文件filename中的数据读入,并且保存为M,filename中只能包含数字,并且数字之间以逗号分隔。M是一个数组,行数与filename的行数相同,列数为filename列的最大值,对于元素不足的行,以0补充。
