I have exported .csv values from an oscilloscope for a unitstep fucntion of a DC motor. I need to find gain K and the transfer function. I get the plots from importing data, but how do i use matlab to caculate the transfer function and the gain

To add to what the above user @thoughtGarden said, the System Identification Toolbox will help you to get mathematical models from your measured input-output data.
In particular, you can look into this Linear Model Identification documentation to identify and predict the transfer function.
