Determine if input is string array with one element
tf = isStringScalar(A)
example
tf = isStringScalar(A) returns 1 (true) if A is a string array and A has only one element. Otherwise, it returns 0 (false).

Create different arrays, and then determine if they are string scalars.
Test a string scalar.
str = "Mercury"
tf = isStringScalar(str)
tf = logical 1
Test a string array with multiple elements. Since str contains more than one element, isStringScalar returns 0.
str
isStringScalar
str = ["Mercury","Gemini","Apollo"]
str = 1x3 string "Mercury" "Gemini" "Apollo"
tf = logical 0
Test a character vector. Since character vectors are not strings, isStringScalar returns 0.
chr = 'Pluto'
tf = isStringScalar(chr)
Input array, specified as an array of any size and data type.
