How to read in a text file with data seperated by a colons and semicolos?

Good morning!

I could use some help. I have a .txt file which I have to read a treat but it has a format different to what Matlab understand. It looks like this:

• 0,40125;-0,0311547518
• 0,40150;-0,0278959572
• 0,40175;-0,0236756057
• 0,40200;-0,0188543797
• 0,40225;-0,0168816000

and so on. I would like to read the first column and put in a vector and after that, read the second column and put it in another vector. What I would need looks like this:

• 0.40125,-0.0311547518
• 0.40150,-0.0278959572
• 0.40175,-0.0236756057
• 0.40200,-0.0188543797
• 0.40225,-0.0168816000

So, here, I would need either a way to convert it to the second sample or just a way to be able to read the data and directly create the arrays.

Any help is greatly appreciated. Thanks, Juan

You'll have to use textscan:

fid = fopen('myfile.txt', 'rt');
m = textscan(fid, '%d,%d;%f');
fclose(fid);
