Description
The
?trnlsp_check
 routine checks the arrays passed into the solver as input parameters. If an array contains any
INF
 or
NaN
 values, the routine sets the flag in output array
info
(see the description of the values returned in the Output Parameters section for the
info
 array)
.
Input Parameters
handle
Type
_TRNSPBC_HANDLE_t
.
n
Length of
x
.
m
Length of
F
(
x
).
fjac
Array of size
m
 by
n
. Contains the Jacobian matrix of the function.
fvec
Array of size
m
. Contains the function values at
X
, where
fvec
[
i
]
= (
y
i
 –
f
i
(
x
))
.
eps
Array of size 6; contains stopping criteria.
See the values in the Description section of the
?trnlsp_init
.
Output Parameters
info
Array of size 6.

 array contains a value less than or equal to zero.
res
Information about completion of the task.
res
 =
TR_SUCCESS
 - the routine completed the task normally.
TR_SUCCESS
 is defined in the
mkl_rci.h
 include file.

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.
