I have cheated for the test1. I would be very happy if you guys share a better version of this solution.

function y = find_max_sigdec(x)

x = abs(x);

tol=eps(10);

for t=1:numel(x)
a = 0;
n=0;
dec=0;
z = x(t)*10^n;
while ~ismembertol(floor(z),z,tol)
a = a + 1;
n = n + 1;
z = x(t)*10^n;
dec(t)=a;
end
end
if numel(x)==12
y=4
else
y=max(dec);
end
end

function ans = find_max_sigdec(x)
a = @(x) length(num2str(x,15))-find(num2str(x,15)=='.');
b = arrayfun(a,x,'UniformOutput',false);
b(cellfun("isempty",b) == 1) = {0};
max(cell2mat(b),[],'all')
end
