I want to test a cell array to see if its contents are a string.
The function iscellstr checks to see if the contents of the cell are a character vector, not a string. Bad naming of a function in my opinion.
I am trying to test the cell array element if it is a string for error checking prior to use. This would be similar to isnumeric.

a={'abc', 123, 'xyz',0};
b=cellfun(@isstr,a)
b = 1×4 logical array
1 0 1 0

The example you used are character vectors ( single quotes ). The strings that are generated are double quotes. Your suggestion did allow me to figure out how to use the function isstring on the cell array elements.
a = {"abc", 123, 'xyz', 0};
b=cellfun(@isstring,a)
b =
1×4 logical array
1 0 0 0
Thank you
