What if name has < 6 characters?
Is there some short way or do have have to write
out = name(1:min(6,length(name)));
substr seems to require some stateflow package https://se.mathworks.com/help/stateflow/ref/substr.html

Ran in:
name = 'Microsoft';
name(1:min(end,6))
ans = 'Micros'
name = 'Cat';
name(1:min(end,6))
ans = 'Cat'

This wasn't an option when the question was originally asked, but the extractBefore function will work for both char vectors and string arrays.
c = 'Microsoft'
c = 'Microsoft'
c6 = extractBefore(c, 7)
c6 = 'Micros'
s = string(c)
s = "Microsoft"
s6 = extractBefore(s, 7)
s6 = "Micros"
