Array container type

Container type for arrays

Model Configuration Pane: Code Generation / Code Style

Description

Specify the container type for arrays in the generated code. Choose either C-style array or std::array.

Dependencies

To enable this parameter, set Language to C++ and set Code interface packaging to C++ class.

Settings

C-style array (default) | std::array

Default: C-style array

C-style array

The code generator generates array containers by using C-style arrays.

std::array

std::array is a template class that represents fixed-size arrays. If you choose this option, the code generator generates array containers by using std::array.

Examples

Compare the array container types in the generated code when you set Array container type to different values.

Here is generated code that generated using the default Array container type value C-style array:

real_T const_val[4] = { 1.0, 2.0, 3.0, 4.0 } ;

Here is the same code generated with Array container type set to std::array:

std::array<real_T, 4> const_val = { { 1.0, 2.0, 3.0, 4.0 } };
