I have a matrix of 1x1000 and another matrix of 1x10. How can I plot these two against each other?

I have a (1 x 1000) and a (1 x 10) matrix. I want to plot these together. How can I do that?

I'm not quite sure what you mean by "plot these two against each other". How many points would you want to appear on the axes when executing this smaller example, and EXACTLY where would you want those points to appear? Would there be anything special or unusual about any or all of those points? Different colored markers, different sized markers, different markers entirely, etc. [Note that this will NOT work as written; there is no plotForShrivathsaS function. If such a function were to exist, how should it behave?]
x1 = [1 2 3 4];
x2 = [5 6 7];
plotForShrivathsaS(x1, x2)

x1 = rand(1,100) ;
x2 = rand(1,10) ;
%%plo tonly matrices
plot(x1,'r') ;
hold on
plot(x2,'g') ;
legend('data1', 'data2');

@KSSV this code plots x1 and x2 individually. i want to plot with x1 on x-axis and x2 on y-axis.

x = rand(1,100) ;
y = rand(1,10) ;
%%plot only matrices
plot(x, zeros(size(x)), 'r*-') ;
hold on
plot(zeros(size(y), y, 'g*-') ;

[X, Y] = ndgrid(x1000, y10);
scatter(X(:), Y(:))
