An interpolation formula for a function of one variable with a boundary layer component is constructed. Such function corresponds to the solution of a singular perturbed problem. The estimate of an accuracy is obtained. On a base of the constructed interpolation formula the difference formulas for derivatives of the function with a boundary layer component are obtained. Numerical resultes are discussed.
Keywords: function, boundary layer, difference formula for a derivative, accuracy estimation.
Mots-clés : nonpolynomial interpolation
