Use memset to initialize floats and doubles to 0.0

Assignment of float and double zero with memset

Description

App Configuration Pane: Advanced

Configuration Objects: coder.MexCodeConfig | coder.CodeConfig | coder.EmbeddedCodeConfig

The Use memset to initialize floats and doubles to 0.0 parameter specifies whether to use the memset optimization for assignment of float and double zero.

Settings

On

This value is the default value.

If possible, the code generator uses the memset optimization for assignment of floating-point zero to consecutive array elements. To assign consecutive array elements, the memset optimization uses a memset call. When the number of elements to assign is known at compile time, the code generator uses the Memcpy threshold (bytes) property to determine whether to use the optimization.

Off

The code generator does not use the memset optimization for assignment of float and double zero to consecutive array elements.

Programmatic Use
