Hi guys,
I am trying to write max() and min but our teacher said you cannot use max() and min() function. how can ı write alternativly these functions. I have done mean value like that:
if length(m)==4
element=element+1;
s =sum(m) / 4;
arc = [arc s];
m=[];
end
every 4 step m function reset and also values that have been in m (m has 4 element at the moment) sums and divide 4. the new value (mean value of a at the moment) goes arc.
I want to da that max and min version without max and min command but this time the values has to go new set that ı called maxvalues and min values could someone help me ?

Ugur, post the image directly here with the green and brown frame icon, not on some third party web site.

minvalue=a(1);

maxvalue=x(1);
minvalue=x(1);
for k=2:length(x)
if x(k)>maxvalue
maxvalue=x(k);
elseif x(k)<minvalue
minvalue=x(k);
end
end
