I have a column of data and I want to make a script that utilizes for loops and if constructs

for example

In this set, the minima would be 4 and 6

Hope this helps. Vector y returns the minimum values of vector A

A=[12; 4; 5; 23; 63; 57; 23; 6; 34];
a=A';
d=[diff(a) 0];
c=[];
for i=1:(length(d)-1)
    if d(i)*d(i+1)<0&&d(i+1)>0
        c=[c (i+1)];
    end
end
for j=1:length(c)
    y(j)=a(c(j));
end

This is homework.

We have a policy of providing only hints for homework. It is not appropriate to provide complete solutions.

I am sorry. I did not know of that. I will do that in future
