How do I replace data in a dataset?

I'm using a dataset that I generated from the output of a lab mate's code, and all of the "no data" values are currently listed as -1. I want to change all of the -1 values to NaN so that I can start to run stats on the data. Is there a way that I can do this? The variables in question are doubles (so I can't use strrep), but my dataset also has other variable types.

Dat = [-1 2 3 4 5 6 -1 4.3 pi -1]
Dat(Dat==-1) = nan

Thank you! You are a life saver! (or at least a Tuesday-saver)
