If loop not acting properly??
显示 更早的评论
Hello, just looking for some quick help. How come when I execute this code, the only value for which .003 shows up is the 101st iteration of i?
for i = 1:101
if (i>=84)
a = .003;
elseif (i<84) && (i>=38)
a = 0;
elseif (i<38)
a = -.0065;
end
end
temp_si(i) = a

move the last line inside the for-loop.

And add temp_si=zeros(1,101) before the for-loop to pre-allocate memory.
So either:
temp_si = zeros(1, 101);
for i = 1:101
if (i>=84)
a = .003;
elseif (i<84) && (i>=38)
a = 0;
elseif (i<38)
a = -.0065;
end
temp_si(i) = a
end
or:
temp_si = zeros(1, 101);
temp_si(1:37) = -0.0065;
temp_si(84:101) = 0.003;
Of course I prefer the latter.
