Method Detail

f

Matrix f(double... x)

Computes a matrix based on multivariate input

Parameters:

x - the variables to evaluate as part of the function

Returns:

the matrix output of the function

f

Matrix f(Vec x)

Computes a matrix based on multivariate input

Parameters:

x - the variables to evaluate as part of the function

Returns:

the matrix output of the function

f

Matrix f(Vec x,
         Matrix s)

Computes a matrix based on multivariate input

Parameters:

x - the variables to evaluate as part of the function

s - the matrix to store the result in, or null if a new matrix should be allocated

Returns:

the matrix containing the results. This is the same object as s if s is not null

f

Matrix f(Vec x,
         Matrix s,
         ExecutorService ex)

Computes a matrix based on multivariate input

Parameters:

x - the variables to evaluate as part of the function

s - the matrix to store the result in, or null if a new matrix should be allocated

ex - the source of threads to use for the computation

Returns:

the matrix containing the results. This is the same object as s if s is not null
