Dynamic array container type - Container type for dynamic arrays - MATLAB (original) (raw)

Main Content

Container type for dynamic arrays

Since R2024b

Model Configuration Pane: Code Generation / Code Style

Description

Specify a container type for 1-dimensional dynamic arrays in the generated code. Choose either coder::array or std::vector.

This parameter affects only 1-dimensional dynamic arrays. For higher-dimensional dynamic arrays, the code generator generates coder::array containers regardless of the value of this parameter.

Dependencies

• To enable this parameter, set the Language model configuration parameter toC++.

Settings

std::vector (default) | coder::array

Default: std::vector

std::vector

The code generator generates std::vector containers to represent 1-dimensional dynamic arrays.

coder::array

The code generator generates coder::array containers to represent 1-dimensional dynamic arrays. If you open a model that was created before R2024b, the model defaults to this setting.

Examples

Consider this model, myModel:

The model passes an unbounded variable-size 1-dimensional signal from anInport block to an Outport block. If you set theDynamic array container type model configuration parameter to std::vector, the code generator produces this code inmyModel.h:

// External inputs (root inport signals with default storage) struct ExtU_myModel_T { std::vector Input; // '/Input' };

// External outputs (root outports fed by signals with default storage) struct ExtY_myModel_T { std::vector Out1; // '/Out1' };

If you set the Dynamic array container type model configuration parameter tocoder::array, the code generator produces this code instead:

// External inputs (root inport signals with default storage) struct ExtU_myModel_T { coder::array<real_T,1> Input; // '/Input' };

// External outputs (root outports fed by signals with default storage) struct ExtY_myModel_T { coder::array<real_T,1> Out1; // '/Out1' };
