Label scatter data points.

I have a matrix C as follows;

 1 3 0.454 54
 3 4 0.478 0.356
 7 8 4.564 1546

And I plot, scatter(C(:,3),C(:,4))

I want to label every data point as first two columns of matrix. Like, label (0.454,54) as 1 3, (0.478,0.356) as 3 4 and so on.

text( C(:,3),C(:,4), cellstr(str2num(C(:,1:2))) )

Hey thanks for a reply, but this gives error Error using str2num (line 32) Requires string or character array input. May be I cant use matrix as an input for str2num.

Sorry, I have been up all night ;-(

text( C(:,3),C(:,4), cellstr(num2str(C(:,1:2))) )
