So, I think I have found an error in the way matlab's built in jsonencode() function works. If you create a struct with one field of doubles, and a double has a infinity value (inf or -inf) jsonencode will encode this without quotation ("") marks. Therefore if I put this through a JSON validator (https://jsonlint.com/) it fails. I am using JSONLab toolbox in the meantime, however it would be nice to work with the native matlab function. Here is the code for an example:
x(1).a = 'hello'
x(1).b = 12
x(2).a = 'bye'
x(2).b = -inf
example = jsonencode(x)
Which will then output:
[{"a":"hello","b":12},{"a":"bye","b":-Inf}]
Where infact the correct output should be:
[{"a":"hello","b":12},{"a":"bye","b":"-Inf"}]
