Accessing data of notepad

I have notepad data like this:

-1 1:0.009 2:-0.056 3:6.009

The data is in rows and columns while every row starts with 1 or -1. When I try to access data in matlab, e.g:

data=load('*.txt')
X=data(1,:)

I will get -1 1 2 3 which represent the no. of data point not actual data, rather 0.009 0.056 6.009 which is actual data. Can anyone help me with this?

An alternative to a simple load is to use fscanf or textscan, as in

fid=fopen('accessing_data_of_notepad.txt')
dat = textscan(fid,'%s')
fclose(fid)

Your data will be in cell array dat. You can modify the format specifier to suit your needs, for instance if you want all of the numbers you can use something like 

fid=fopen('accessing_data_of_notepad.txt');
dat = textscan(fid,'%d %d:%.3f %d:%.3f %d:%.3f')
fclose(fid);

Values 0.009 0.056 6.009 will be in dat{3}, dat{5} and dat{7}
