how to convert a vector to a number

hi lets say i have a vector [1,1,1] is there a function that can convert this to the number 111 ?

What should be done if the vector includes values greater than 9?

If the vector starts with values that are 0, what should be the result ?

the vector does not contain values greater than 9. if it has 0 to the left it ignores them - 009=9, 012=12 etc.

i could write a for loop that calculates this but i was wondering if there is a function.

Answer 1

 a = randi(9,1,5); 
 your_num = sscanf(sprintf('%d',a),'%d');

or

 alt_sol = sum(a.*repmat(10,1,numel(a)).^(numel(a)-1:-1:0));
