How do I print a string and an array on the same line or with one function call?

Currently, I have to write two lines of code as shown below to display a string followed by the values in my array. I do this by calling "disp" twice:

>> disp('Your array is')

Your array is

>> disp([1 2; 3 4])

     1     2

     3     4
I am looking for a faster and easier way to display a string and then an array.

It would be great if there was a MATLAB function that could do this. Having a MATLAB function to do this in one line would improve the simplicity of my code while saving me a lot of time and effort.

There are a couple of workarounds you can use to print a string and then an array in one function call:
1.      Use the "sprintf" command with "%s" as shown below, where A = [1 2; 3 4]:
>> sprintf("Your array is %s", mat2str(A))
ans =
"Your array is [1 2;3 4]"
2.      Create your own function that achieves the output you desire, and add the folder holding this function to your MATLAB search path to call this function anywhere.
