How to create a row from x(1) to x(n)?

Hello

I am quite new to coding and trying to create a row where each term in the row is x followed by the column number in brackets. So [x(1) x(2) x(3) ... x(n)]

Many thanks

I suggest going through MATLAB Onramp. Chps 4 and 5 seems to be relevant to what you are asking.

You might also just be needing to transpose you column vector to turn it into a row vector. Use ' for that. This is covered in 4.2.6.

x=[1:5]'

x = 5×1

1 2 3 4 5

●

x1=x'

x1 = 1×5

1 2 3 4 5

Thanks for the rsponse, I will have a look. I'm not looking for a row of numbers, but rather of strings where each string is 'x(n)' where n is the column number. So in your answer I need x1 to be x(1) x(2) x(3) x(4) x(5).

Ok, that is pretty simple as well, but not covered in Onramp.

x1 = "X(" + string(1:5) + ")"

x1 = 1×5 string array
    "X(1)"    "X(2)"    "X(3)"    "X(4)"    "X(5)"

Try this:

n = 5;
for k = 1 : n
	str(k) = string(sprintf('x(%d)', k));
end
str % Display in command window

You'll see:

str =

1×5 string array

"x(1)" "x(2)" "x(3)" "x(4)" "x(5)"
