Have to read in the .dat file and then save as .mat. Can't just change a file format from one to the other.

You can employ a few built in data import functions of MATLAB to read your data and then save them in *.mat file. E.g:
FN = 'MY_DATA.dat'; % Introduce your *.dat file name
FID=fopen(FN,'r');
T=10; % Introduce the time length
DATA=fread(fid,2*360*T,'ubit12'); % Adjust w.rt. your data, respectively
save('MY_data.mat', 'DATA');
fclose(FID)
Good luck

I've never even heard of PhysioNet. It took me 15 min to do a web search and figure it out. Just sayin.
There's a basic overview here with links for the WFDB toolbox for Matlab. Download/install the toolbox.
Once it's installed, run
help wfdb2mat
and maybe try the example:
wfdb2mat('mitdb/200')
This downloads the specified dat file and makes a local copy as a .mat file with an associated .hea file.
The toolbox also includes other tools for further operation on the data.
