MATLAB: Forcing a scalar to be represented as a 1×1 vector

1x1 vectorjsonencodeMATLAB

Is it possible to force a scalar to be represented in vector form? The purpose for this is to encode a vector in json format. If a vector has size 1 I would like it to still encode to json as a vector and not a scalar.
In the example below variables 'a' and 'b' encode to json as intended but I would like 'c' to encode as '[4]' and not '4'.
a = [1, 2];
b = 3;
c = [4];
jsonencode(a) % ans = '[1,2]'
jsonencode(b) % ans = '3'
jsonencode(c) % ans = '4'

Best Answer

By the table in the documentation,
>> jsonencode({c})
ans =
    '[4]'
