Extension of UnivariateMatrixFunction representing a univariate differentiable matrix function.
Since:3.1
/** * Extension of {@link UnivariateMatrixFunction} representing a univariate differentiable matrix function. * * @since 3.1 */
public interface UnivariateDifferentiableMatrixFunction extends UnivariateMatrixFunction {
Compute the value for the function.
Params:
  • x – the point for which the function value should be computed
Throws:
  • MathIllegalArgumentException – if x does not satisfy the function's constraints (argument out of bound, or unsupported derivative order for example)
Returns:the value
