Hi
I have 3 coloumns of scalar data, each coloumn belongs to the data of a particular parameter. I have to plot the three parameters in a contour figure. Before that I have to convert the scalar data into a complex one. How shall I do this?

A scalar can be complex by definition. A scalar is just a number. So I'm assuming you have real-valued data to start with. How are you going to determine the imaginary part?
You can simply make the attribute complex by
z = randn(100,3);
z = complex(z);
but to actually give it some meaningful imaginary part, you have to some way to assign it.
z = randn(100,3);
z = z+1j*ones(size(z));

You have to have some way of assigning the imaginary part. If you are starting with real valued data, I don't know how you want to assign the imaginary part.
