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

%% This script gives how many times Easter occurs on the dates during the century.

c = zeros(1,31);

for year = 2000:2100

dn=easter(year);

fulldate=datevec(dn);

date=fulldate(3);

c(date) = c(date) + 1;

end

%% This script gives how many times Easter occurs in March/April in the century.

Easter_in_March = 0;

Easter_in_April = 0;

for y = 2000:2100 % 21 st century

g = mod(y,19) + 1;

c = floor(y/100) + 1;

x = floor(3*c/4) - 12;

z = floor((8*c + 5)/25) - 5;

e = mod(11*g + 20 + z -x, 30);

if (e == 25 && g>1 e==24)

e = e + 1;

end

n = 44 - e;

if n<21

n = n + 30;

end

d = floor(5*y/4) - x - 10;

d = n + 7 - mod(d+n,7);

if d <32

Easter_in_March = Easter_in_March + 1;

else

Easter_in_April = Easter_in_April + 1;

end

end

fprintf('in 21st Century \n%g times Easter occurs in March', Easter_in_March)

fprintf('\n%g times Easter occurs in April', Easter_in_April)

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).
