MATLAB: Beginner… why a matrix with numbers and strings doesn’t give me the numbers? ( I know I have to transform the numbers into strings)

Question

I just would like to know how it works.

e.g

t = 71 ;
c = (t-32)/1.8 ;
hey = ['The temperature is , c , 'C']

1. it's not going to work! I have to use a command to transform "c".why???

a = [ 'how's it going' , 10 , 'cool' ]

it will give me both strings but not the number 10 ….

it looks like there's no "10" in "a" ..

thanks for helping

Answer 1

a = [ 'how''s it going' , num2str(10) , 'cool' ];

or

a = sprintf('how''s it going %d cool' 10];

or

a =  sprintf('%s %d %s', 'how''s it going', 10, 'cool' ];
