System objects in DSP System Toolbox that Support SIMD Code Generation

When certain conditions are met, you can generate SIMD code using Intel AVX2 technology from certain MATLAB^® System objects in DSP System Toolbox™. For information on how to generate SIMD code from MATLAB algorithms, see Generate High Performance SIMD Code on Intel from MATLAB Algorithms in DSP System Toolbox.

The following table contains a list of System objects in DSP System Toolbox that support SIMD code generation. The table also details the conditions under which the support is available.

MATLAB System objects	Conditions
