Need a space in strcat comand

V = [1 2 3 4 5];

strcat ('R = ', strjoin(string( V),', '))

I got the following answer while running the above code

"R =1, 2, 3, 4, 5"

But i need (a white space after '=' sign)

"R = 1, 2, 3, 4, 5"

The solution is already given in the STRCAT documentation:

V = 1:5;
strcat({'R =   '},strjoin(string( V),', '))

ans = "R =   1, 2, 3, 4, 5"

You can use strjoin again -

V = [1 2 3 4 5];
out1 = strjoin(["R =" strjoin(string(V),', ')])

out1 = "R = 1, 2, 3, 4, 5"

You can also add strings like this -

out2 = "R = " + strjoin(string(V),', ')

out2 = "R = 1, 2, 3, 4, 5"

V = [1 2 3 4 5];
str = sprintf('R = %s', strjoin(string( V),', '))

str = 'R = 1, 2, 3, 4, 5'
