In C/C++ progromming language the symbol '%' used for remining value but in the MATLAB the percentile symbol(%) used as commnet. In MATLAB if conditioning other than 0 for all values it is true so you got always 1 for your function
MATLAB is very rich in documentation please read MATLAB basics
It can be optimized in one line statement rather than using as function
result = (mod(a, 4) == 0)
