Use JIT compilation for build type of MEX

Just-in-time (JIT) compilation mode

Description

App Configuration Pane: Advanced

Configuration Objects: coder.MexCodeConfig

Just-in-time (JIT) compilation mode.

To speed up generation of MEX functions, set EnableJIT to true.

JIT compilation is incompatible with certain code generation features and options, such as custom code or use of the OpenMP library. If you specify JIT compilation and the code generator is unable to use it, it generates a C/C++ MEX function with a warning. If EnableJIT and EnableOpenMP are true, and your code uses parfor, the code generator uses JIT compilation and treats the parfor-loops as for-loops.

See Speed Up MEX Generation by Using JIT Compilation.

Settings

Off

This value is the default value.

The code generator creates a C/C++ MEX function by generating and compiling C/C++ code.

On

The code generator uses just-in-time (JIT) compilation technology for MEX function generation. The code generator creates a JIT MEX function that contains an abstract representation of the MATLAB^® code. When you run the JIT MEX function, MATLAB generates the executable code in memory.
