There is no inbuilt MATLAB function that converts numeric values to words, but you can use my FEX submission num2words to do exactly this:

It has been extensively tested, and has lots of useful options too.

Here are some examples:

num2words(0) 
 ans = 'zero'

num2words(-1024) 
 ans = 'negative one thousand and twenty-four'

num2words(pi, 'order',-10) 
 ans = 'three point one four one five nine two six five three six'

num2words(intmax('uint64'), 'sigfig',3, 'type','highest') 
 ans = 'eighteen point four quintillion'
