Functions

`jsondecode`	Decode JSON-formatted text
`jsonencode`	Create JSON-formatted text from structured MATLAB data
`readstruct`	Create structure array from file
`writestruct`	Write structure array to file
`readdictionary`	Create dictionary from file (Since R2024b)
`writedictionary`	Write dictionary to file (Since R2024b)
