Array layout

Layout (column-major or row-major) code generator uses for array data

Model Configuration Pane: Code Generation / Interface

Description

The Array layout parameter specifies the layout that the code generator uses for array data. The layout can be column-major or row-major.

Settings

Column-major (default) | Row-major

Column-major

Generates code in column-major array layout. For example, consider matrix A, which is a 4x3 matrix:

A =
    1    2    3
    4    5    6
    7    8    9
    10   11   12

In column-major array layout, the elements of the columns are contiguous in memory. A is represented in the generated code as:

1    4    7    10    2    5    8    11    3    6    9    12

Row-major

Generates code in row-major array layout. For example, for matrix A, in row-major array layout, the elements of the rows are contiguous. A is represented in the generated code as:

1    2    3    4    5    6    7    8    9    10    11    12

Select parameter Use algorithms optimized for row-major array layout to enable efficient row-major algorithms.
