Question

I have something like the following:

A = [1 2 5; 1 5 7];

B = A(1,:);

I output B:

B = A(1,:);

B =

 1     2     5

I am looking to combine what is contained in B into one single string:

1/2/5

Answer 1

You can use sprintf:

sprintf('%d/',B)

This will give you almost what you want, it will have unnecessary / in the end.

>> sprintf('%d/',B)

ans =

1/2/5/

If you want to remove it:

st = sprintf('%d/',B);
st(end) = [];

As @hmuster points out correctly, it is possible to do it with \b , the backspace character.

st = [sprintf('%d/',B) sprintf('\b')];

However, as @AndrewJanke points out correctly, it could become a problem if this string is written into a pipe or a file. So use it with caution.
