MATLAB: How to replace commas with periods in data

commasdatadecimalsimporting datastrings

I am importing some data that originated in Germany, and they used commas instead of periods to indicate decimals. Now my issue is that when I import the data, I would like to import the data as a double, but I can't because the commas are treated as strings and not as decimal places. Any work around for this (replacing the commas with periods or something)?
