Text inputs. For example, specifying a character vector as the input argument produces an error.

function d = foo() %#codegen
    d = datetime('2019-12-01');
end

The 'Format' name-value pair argument. You cannot specify the display format by using the datetime function, or by setting the Format property of a datetime array. To use a specific display format, create a datetime array in MATLAB, then pass it as an input argument to a function that is intended for code generation.

The 'TimeZone' name-value pair argument and the TimeZone property. When you use datetime arrays in code that is intended for code generation, they must be unzoned.

Setting time component properties. For example, setting the Hour property in the following code produces an error:

d = datetime;
d.Hour = 2;

Growth by assignment. For example, assigning a value beyond the end of an array produces an error.

function d = foo() %#codegen
    d = datetime(2019,1:12,1,12,0,0);
    d(13) = datetime(2020,1,1,12,0,0);
end

Deleting an element. For example, assigning an empty array to an element produces an error.

function d = foo() %#codegen
    d = datetime(2019,1:12,1,12,0,0);
    d(1) = [];
end

Converting datetime values to text by using the char, cellstr, or string functions.
