Normalized Sinc using matrix inputs

My code is to use the formula sinc(x) = sin(x*pi)/(x*pi) to return a matrix of the same size as the input, and when dealing with a element equal to zero, it is to return a value of one.

function y = normsinc(vec)
y = sin(vec)*pi ./ (vec*pi);

This is what I have right now, but it can't use if statement to check the values of the input. I get the same size output as the input but for zeros I get NaN.

" but it can't use if statement to check the values of the input." - why not?

Its school work and they have 'tests' to check that the code follows their guidelines.

What about appending:

y(isnan(y)) = 1;
