The values in a datetime array represent points in time using the
proleptic ISO calendar.
When you use datetime arrays with code generation, adhere to these
restrictions.
For code generation, use the datetime function to create
datetime arrays. For example, suppose the input arguments to your
MATLAB® function are numeric arrays whose values indicate the year, month, day, hour,
minute, and second components for a point in time. You can create a
datetime array from these input arrays.
function d = foo(y,mo,d,h,mi,s) %#codegen d = datetime(y,mo,d,h,mi,s); end
For code generation, you are restricted to the operations on datetime
arrays listed in this table.
| Operation | Example | Notes |
|---|---|---|
Assignment operator: |
d = datetime(2019,1:12,1,12,0,0); d(1) = datetime(2019,1,31); | Code generation does not support using the assignment operator
|
Relational operators: |
d = datetime(2019,1:12,1,12,0,0); tf = d(1) < d(2); | Code generation supports relational operators. |
Indexing operation |
d = datetime(2019,1:12,1,12,0,0); idx = [1 2]; d(idx); idx = logical([1 1 0]); d(idx); | Code generation supports indexing by position, linear indexing, and logical indexing. |
Concatenation |
d1 = datetime(2019,1:6,1,12,0,0); d2 = datetime(2019,7:12,1,12,0,0); d = [d1 d2]; | Code generation supports concatenation of |
