I’m not exactly sure what you mean, perhaps:

vector(repmat([3,4,5],1,10))

edit:

vector(sort([3:12:360,4:12:360,5:12:360]))

Adapt this into your problem:

A=randi([1 5],194,201,360);
B=randi([1 5],194,201,30);
for i=120:270
    A(:,:,i)./B(:,:,1:30);
end

MATLAB: I modified Easter.m to give me how many times and on what dates Easter occurs in March/April in a century. How to use that to make a vector to check for all the dates Easter can’t occur

All the functions you use support array inputs, so you only need to change you if-statements to logical indexing (use the condition as index, after replacing double ampersand with a single one).
