Intel® oneAPI Math Kernel Library Developer Reference - Fortran
The TR routine names have the following structure:
<character><name>_<action>( )
where
<character> indicates the data type:
real, single precision
real, double precision
<name> indicates the task type:
nonlinear least squares problem without constraints
nonlinear least squares problem with boundary constraints
computation of the Jacobian matrix using central differences
<action> indicates an action on the task:
initializes the solver
checks correctness of the input parameters
solves the problem
retrieves the number of iterations, the stop criterion, the initial residual, and the final residual
releases the allocated data
