Creating cell arrays of strings using the {} operator is discouraged. To concatenate strings into a string array, use square brackets instead. Then, you can index into, manipulate, and compare the text in the string array.

For example, suppose you have a string array that contains three strings. You can find the strings that start with the letter S in str with the startsWith function.

startsWith(["Skylab" "Skylab B" "ISS"], "S")


Using the startsWith function with a cell array of strings returns an error.

Replace the braces surrounding the strings with square brackets.

For example, replace code such as {"Skylab" "Skylab B" "ISS"} with ["Skylab" "Skylab B" "ISS"].
