Create different arrays, and then determine if they are string scalars.

Test a string scalar.

str = "Mercury"
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 = ["Mercury","Gemini","Apollo"]
str = 1x3 string array
    "Mercury"    "Gemini"    "Apollo"

tf = isStringScalar(str)
tf = logical
   0

Test a character vector. Since character vectors are not strings, isStringScalar returns 0.

chr = 'Pluto'
chr = 
'Pluto'
tf = isStringScalar(chr)
tf = logical
   0
