Array Layout

Column-major and row-major order for array storage

Array layout refers to the order in which array elements are stored in memory. By default,MATLAB^®Coder™generates code that uses column-major layout. You can also generate code that uses row-major. Row-major layout can improve performance for certain algorithms and ease integration with external code or data that uses row-major. Linear indexing operations always use column-major layout in generated code.

Functions

`codegen`	Generate C/C++ code fromMATLABcode
`coder.ceval`	Call external C/C++ function
`coder.columnMajor`	Specify column-major array layout for a function or class
`coder.isColumnMajor`	Determine whether the current function or variable uses column-major layout
`coder.isRowMajor`	Determine whether the current function or variable uses row-major layout
`coder.rowMajor`	Specify row-major array layout for a function or class

Classes

`coder.CodeConfig`	Configuration parameters for C/C++ code generation fromMATLABcode
`coder.MexCodeConfig`	Configuration parameters for MEX function generation fromMATLABcode
`coder.EmbeddedCodeConfig`	Configuration parameters for C/C++ code generation fromMATLABcode withEmbedded Coder
