string.startsWith
string: TF = startsWith (str, pattern)
string: TF = startsWith (str, pattern, 'IgnoreCase', true)
Test if strings start with pattern.
TF = startsWith (str, pattern) returns a logical
array TF of the same size as A containing true for
each corresponding element of str that starts with the specified
pattern and false otherwise. Similarly to NaN
values, <missing> elements do not match any pattern and always
return false.
TF = startsWith (str, pattern,
ignores case when determining if
str starts with pattern.
