Arrange data using loop in MATLAB

If I have:

  t=(1:1:5)'
  time=1:3:100

How do I arrange data t in each column starting from 1 until the end, with an interval of 3. Which means that the data t (1 to 5) at column 1,4,7 and so on.

I've tried:

t=[1:1:5];
nt=length(temp);
time=[1:1:100];
nti=length(time);
x=zeros(nt,nti);

temp=temp';
initiator=2;
monomer=3;

post=1:3:100;

for l=1:post

step=1;
maxstep=100;
 while (step<maxstep)
    step=step+3;
    temp=(1:1:5)';
 end
t(:,l)=t;
x=[t];

end

This only shows result X with temp at column 1. I do not know开发者_如何学运维 how to to arrange this data at columns that I want.

Hope someone will help me. Thank you in advance.

How many dimensions does your data have? If you already have "temp" (temperature?) and "time" as your first two dimensions and you want "t" to be the third dimension, then create a three-dimension matrix.

To extract from indexes [1 4 7 10 13 16 ... ], use (1:3:end)
To extract from indexed [2 5 8 11 14 17 ... ], use (2:3:end)

In MATLAB's colon notation, the first value is the start. Second value is increment. Third value is the end value and is inclusive.
