Can you show us what you want as the output? Example:

[Replace below with what you want as the output]

... + "this is a string"  =  "...this is a string"  ??

I got something like this:

a = [1;2;3];
b = [3;2;1];
aa = num2str(a);
bb = num2str(b);
and I want to add a '.' between each two values and get one single array at the end so it would look like this:

'1.3'
'2.2'
'3.1'

Answer 1

I solved it, thnx guys

Answer 2

[Guillaume]

a = [1;2;3];
b = [3;2;1];

Two easy options:

compose('%d.%d', a, b)   %or compose("%d.%d", a, b) to get a string array instead of a cell array of char arrays

or

string(a) + "." + string(b)

[OCDER]

a + "." + b       %this also works

a = [1;2;3];
b = [3;2;1];
idx = [a b]
sprintf('%.f.%.f \n',idx')

Hey, unfortunately it's not like that. It's like this: I want to get cc ofcurse without doing c !

a = [1;2;3];
b = [3;2;1];
aa = num2str(a);
bb = num2str(b);
c = [1.3;2.2;3.1];
cc = num2str(c);
