Asked by Josh Bridges on 27 Nov 2012

Greetings,

I have a 15x2 matrix that looks like this:

1500 0

220 80

220 75

220 70

220 65

275 70

275 75

275 80

285 80

285 75

300 80

300 70

300 60

220 30

300 40

From this matrix, I have to separate the two columns into different variable in column vector form, but I don't need the first row(this is another task I was able to do) and I MUST use a loop per the instructions.

So far, I have:

for l = 1:d

if datain(l)>100

if datain(l)<=300

PH1(m) = datain(l);

PH = PH1';

m = m + 1;

end

end

end

m = m - 1;

for k = datain

LA = k(2:15,1);

end

Technically, this works, somewhat, but I don't think it's what the professor is looking for. Any help would be greatly appreciated.

This runs, but does not do what you expect:

for k = datain LA = k(2:15,1); end

For each element of `datain` the variable LA is overwritten by the vektor `k(2:15,1)`. Therefore the FOR loop can be omitted.

What is `d` in your code?

Why do you assume, that the professor wants something else?

Please learn how to format code in the forum. Currently the code looks ugly.
