Question

I have a 2 d matrix like this:

0   0   0   0   0   0
0   0   0   0   0   1
0   0   0   0   1   0
0   0   0   0   1   1
0   0   0   1   0   0
0   0   0   1   0   1
0   0   0   1   1   0
0   0   0   1   1   1
0   0   1   0   0   0
0   0   1   0   0   1
0   0   1   0   1   0
0   0   1   0   1   1

1   1   1   1   1   0
1   1   1   1   1   1

I want to convert this matrix into something like the following:

100000
100001
100010

and so on…

Answer 1

The answer from @Shai might be what you are looking for, but I read your question to ask about how to concatenate the rows of the matrix to form a vector.

It then depends on what type of format you want for your output, but here is one way to get a vector of numbers instead of the matrix.

>> A = eye(3)

A =

     1     0     0
     0     1     0
     0     0     1

Convert the matrix into string:

>> B = num2str(A)

B =

1  0  0
0  1  0
0  0  1

Extract the chars that correspond to digits (and leave out the spaces):

>> C = B(:,1:3:end)

C =

100
010
001

Here you’ve got your values as strings which might be what you want (even if it is not really a vector). You could also convert this back to numbers, but then you will get an output of the following kind:

>> D = str2num(C)

D =

   100
    10
     1
