string: TF = contains (str, pattern)
string: TF = contains (str, pattern, 'IgnoreCase', true)

Test if strings contain pattern.

TF = contains (str, pattern) returns a logical array TF of the same size as A containing true for each corresponding element of str that contains the specified pattern and false otherwise. Similarly to NaN values, <missing> elements do not match any pattern and always return false.

TF = contains (str, pattern, 'IgnoreCase', true) ignores case when determining if str ends with pattern.
