Determining what type of data is in my array

I'm writing a code to deal with a large data set and I'm not so great with Matlab just yet. I've searched, but I'm wondering if there is a function that asks the question "is this a double?" I need to throw out the data points that report NaN. Or is there another way that I can identify those data points?

x = [1 nan pi]
x2 = x(~isnan(x))
