You could store the names and values in arrays and look up the angle corresponding to the matching name.
directionValues = 0:22.5:337.5
directionNames = {'N','NNE','NE','ENE','E','ESE','SE','SSE','S','SSW','SW','WSW','W','WNW','NW','NNW'};
directionValues(strcmp(directionNames,'NNW'))
Better yet, put that in an anonymous function
compass2degree = @(dirName) directionValues(strcmp(directionNames,dirName));
compass2degree('ESE')
