Matlad read csv file and euclidean distance

I have a csv file with a lot of data The csv file looks like this

12001,0.2,0.32,0.9,....
12002,0.22,0.3,0.5,...
...
I need all this data in a matrix to compute the euclidean distance

to read the csv file I am using dlmread I need the data in a Matrix without the first value of each line, my matrix should look like this

M=[0.2 0.32 0.9; 0.22 0.3 0.5]

How can I skip the first value in each line and get my data into a matrix?
