How to rescale the size of points in scatter plot?

I generated scatter plot for four variables where one variable specify the size of dots. However, all dots are to small. How to increase the size (e.g. twice bigger dots) of all dots automatically?

scatter(A,B,C,D,'filled','MarkerFaceAlpha',.5);

scatter(A,B,C,D,n,'filled','MarkerFaceAlpha',.5);

where n is size of the marker....specify the size you want..

But it is not possible to generate scatter with five variables.

Error using scatter (line 44) Too many input arguments.

[KSSV]

x = rand(10,1) ;
y = rand(10,1) ;
scatter(x,y,100,'filled');

Thank you for your answer, but this not what I am asking. I do not want to have all dots with the same size. As I mentioned in my post I have variable 'C' which specify the size of my dots. However, even the biggest dots are to small and I want to enlarge all dots with the same scale, e.g. to make them twice bigger than they are now.

Multiply your variable size data with a constant number.
