I am new to matlab and attempting to fill an empty array with data from a for loop using a certain column of data (column f). However, when I try and run the code, it just spit backs out the data from column f and doesn't seem to do anything from the for loop but no errors are shown. Please help.
A = readmatrix('filename');
f = A(:,6);
start_c = [150 278 444 554 612 716];
time_c = [48 42 36 42 42 42];
end_c = [start_c + time_c];
start_dc = [96 214 332 388 496 668];
time_dc = [42 48 42 42 42 36];
end_d = [start_dc + time_dc];
crave = 1;
dcrave = 0;
rest = -1;
empty_array = [];
for ii = 1:length(f)
if f(ii) >= start_c & f(ii) <= end_c
crave;
elseif f(ii) >= start_dc & f(ii) <= end_dc
dcrave;
else f(ii)
rest;
end
empty_array(ii) = f(ii);
end

The code does not assign ‘crave’, ‘dcrave’ or ‘rest’ to anything.
What do you want the code to do with those values?
In the interim, perhaps something like:
empty_array = zeros(size(f));
for ii = 1:length(f)
if f(ii) >= start_c & f(ii) <= end_c
empty_array(ii) = crave;
elseif f(ii) >= start_dc & f(ii) <= end_dc
empty_array(ii) = dcrave;
else f(ii)
empty_array(ii) = rest;
end
empty_array(ii) = f(ii);
end
will do what you want.
