Hi! I have Location(1,4).loc that is a 137x19 cell array. I want to find the number of time that first column have value '674' and the consecutive value in the second column is '673'. How can I do?

Use strcmp, which works well for cell arrays of strings. Compare the first column to the string '674' and the second column to '673'.
x = Location(1,4).loc;
sum(strcmp(x(:,1),'674') & strcmp(x(:,2),'673'))
When I ran the above code on the data you provided, I got a result of 13.

I assume you mean something like this?
y = {'1' '256'; '674' '631'; '674' '673'}; %target values
for ii=1:size(y,1)
cnt(ii) = sum(strcmp(x(:,1),y{ii,1}) & strcmp(x(:,2),y{ii,2}));
end
