将CSV扫描到变量 [英] Scan CSV to variables

问题描述

我有这样的CSV（一行）：

  101，120，130 
 
 
  pt_num = 101 
x = 120 
y = 130 
  
 
 
解决方案
只需使用  csvread  ：
  M = csvread（'filename.csv'）; 
 pt_num = M（：，1）; 
 x = M（：，2）; 
 y = M（：，3）; 
  
您也可以使用 textscan 列在单元格数组中：
  fid = fopen（'filename.csv'，'r'）; 
 C = textscan（fid，'％d，％n，％n'）; 
 fclose（fid）; 
  
还有 fscanf 必须重新整形数组：
  fid = fopen（'filename.csv'，'r'）; 
 M = fscanf（fid，'％d，％f，％f'）
 fclose（fid）; 
 M = reshape（M，3，[]）'; 
  
最后， dlmread   csvread ：
  M = dlmread（'filename.csv'，' ，'）; 
  
 
I have a CSV like this (one line):
101, 120, 130
How can I scan these into variables like this:
pt_num = 101
x = 120
y = 130

解决方案
Just use csvread:
M = csvread('filename.csv');
pt_num  = M(:,1);
x = M(:,2);
y = M(:,3);
You can also use textscan to get each column in a cell array:
fid = fopen('filename.csv','r');
C = textscan(fid,'%d, %n, %n');
fclose(fid);
And there is fscanf, but you will have to reshape the array:
fid = fopen('filename.csv','r');
M = fscanf(fid,'%d, %f, %f')
fclose(fid);
M = reshape(M,3,[])';
Finally, dlmread, which works just like csvread:
M = dlmread('filename.csv',',');
