plotting 2 data sets of matrix

i have a matrix, which has 2 columns, 1st column having Voltage values and 2nd column having frequency (vg value at that particular frequency).

Now i need to plot a graph of voltage v/s frequency. can you please let me know, do i do this?

   %code
data=0;
for i=1:10
data(i,1) =i*10;
data(i,2)=3000+i;
end
disp(data);
    % code

A) Don't write arrays unnecessarily in Matlab--

data(:,1)=10*[1:10].';
data(:,2)=3000+[1:10].';

B)

plot(data(:,1),data(:,2))

Work thru examples in "Getting Started" section of Matlab to get a feel for the language syntax/usage of Matlab.
