Convert lat/longs to decimal

Hello,

I'm looking for an elegant solution to a problem I'm having converting lat/long coordinates to their decimal equivalents. I have a cellarray variable, known as fix_coords (see below) containing the latitude and longitude coordinates, which are always in the form of 6 numbers, followed by N or S, then 7 numbers followed by E or W. I would like to be able to output two separate variables, fix_LAT and fix_LONG in the decimal equivalent form as column vectors. How can I achieve this? I have the mapping toolbox.

fix_coords = {'515234N0002206W';'515242N0002242W';'514502N0000624W';'514652N0001500E';'514843N0003903E';'514925N0004745E';'515059N0010849E';'515049N0011013E';'515103N0011114E';'515427N0012534E';'520632N0022638E';'520657N0022919E';'520718N0022957E'}
