Analog output from Matlab to Arduino?!

Hi! I am kind of new interfacing Arduino and Matlab but I am working on a project where I need to use some signal from a data base (ECG signals). Those signals are in .mat format and I use Matlab to plot them. I was wondering is there any way possible where I can send those signals through Matlab and use the Arduino to output them so I can use them as input in other devices or see them in an oscilloscope.

Any help would be appreciated :)


Any updates on how you can send serial continous data from Matlab to arduino??
