MATLAB: Function for concatenating strings with delimiters

Question

As the title says, I'm looking to concatenate character strings with a delimiter. For example, take 'sample','abc','1234','12' and combine them into 'sample_abc_1234_12'

I've written my own simple function for this, but I was just curious if there's a built-in function (similar to strcat) that accomplishes the same task.

Thanks!

Answer 1

Something similar to this:

s={'sample','abc','1234','12'};
b=[sprintf('%s_',s{1:end-1}),s{end}]
