Gets the current NaN checking flag, which indicates whether NaN checking has been turned off or on.
= LAPACKE_get_nancheck
The function returns the current value for the LAPACKE NaN checking flag, which indicates whether or not LAPACKE routines check input matrices for NaNs.
Return Value
An integer value is returned which indicates the current NaN checking status.
The returned flag value is either 0 (OFF) or 1 (ON), even though any integer value can be used as an input parameter for
For example, the following code turns on NaN checking:
LAPACKE_set_nancheck(100); int flag = LAPACKE_get_nancheck(); // flag==1, not 100.

Product and Performance Information


Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
