MATLAB: How to permute all combinations of this vector?

vectors

hello i'm struggling to write code for this problem; I want to display all possible combinations of the vectors of the form (1,b1,b2,b3,…..bN),where bi∈{0,1}

so the first entry of the vector is always 1 and the rest take the value 0 or 1. I then want to print every combination of this. How would you go about coding this ?? thanks for your help in advance

This is one approach:

N = 4 ;
[b{1:N}] = ndgrid([0 1])
c = reshape(cat(N+1, ones(size(b{1})), b{:}), [], N+1)

It might be easier here to use a cell array as such

fid = fopen('example.txt');
sample={}; %empty matrix count=1;
j = 1
tline=fgetl(fid);
while ischar(tline)
    disp(tline);
    sample{j} = tline
    tline=fgetl(fid);
    j = j+1 
end
fclose(fid);

MATLAB: Converting decimal year into julian day or a [Y,M,D] vector?

That's not the correct usage of datevec and datestr.

The first thing you need to do is work out how many days are in that year (ie leap year or not). Then it's just a matter of adding the fractional days multiplied by the number of days in the year to the julian day at the beginning of the year.

Just use MatLab's date numbers for flexibility. The following function should convert your serial year to a MatLab date:

function [num] = ConvertSerialYearToDate( y )
  year = floor(y);
  partialYear = mod(y,1);
  date0 = datenum(num2str(year),'yyyy');
  date1 = datenum(num2str(year+1),'yyyy');
  daysInYear = date1 - date0;
  num = date0 + partialYear * daysInYear;
end

And then you can use datevec to split that into its components, or datestr to turn it into a string, etc.
