If statement inside a while loop MATLAB

I am trying to run an if else statement within a while loop but getting a syntax error: parse error near line 49 syntax error. Can someone help me identify and fix the syntax issue? Thanks!

rainfall_values=[39.9 31.0 42.3 42.1 41.1 28.7 16.8 34.1 56.4 48.7 44.1 42.8 48.4 34.2 32.4 46.4 38.9 37.3 50.6 44.8 34.0 45.6 37.3 43.7 41.8 41.1 31.2 35.2 35.1 49.3 44.2 41.7 30.8 53.6 34.5 50.3 43.8 21.6 47.1 31.2 27.0 37.0 46.8 26.9 25.4 23.0 56.5 43.4 41.3 46.0 44.3 37.8 29.6 35.1 49.7 36.6 32.5 61.7 47.4 33.9 31.7 31.5 59.6 50.5 38.6 43.4 28.7 32.0 51.8]

All of those else if should be elseif.
