Design of Algorithm Base on Similar Structure Solving the Boundary Value Problem of the Composite Normalized Modified Bessel Equation

Based on the similar structure and similar kernel function of the solutions for a type of boundary value problems of the composite normalized modified Bessel differential equation, a new algorithm, called similar constructive algorithm, is proposed for solving this type of boundary value problems. This algorithm is an algebraic method without the need of calculus operations, and therefore, it is an effective but simple approach to the studies of engineering and science problems.
