How to convert NMEA degrees minutes to decimal degrees?

Hi! I have a full dataset that I have analysed and derived, the latitude and longitude are currently in NMEA format which is degrees minutes. I want to ask how I could convert those into decimal degrees or degrees minutes seconds using MATLAB please? I have attached my completed matrix file, the lat is the first column and the lon is second.

a sample of the dataset:

% Lat               lon                  height                   seagrass     seabed

from my understanding the lat is 49 degrees 57.0... minutes etc and same with the lon 6 degrees, 16.9... minutes. I am unsure how to split this into the desired format. Any help would be much appreciated. Thank you very much!!
