Scan CSV to variables

Question

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 = 13         


        

Answer 1

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',',');
