Automatic conversion method, device and equipment of reactor core numerical calculation matrix, and medium

The invention discloses an automatic conversion method, device and equipment of a reactor core numerical calculation matrix and a medium. The method comprises the steps: obtaining a matrix conversioninstruction which comprises the reactor core numerical calculation matrix and a matrix conversion form; querying a matrix conversion derivation table based on the matrix conversion form, and obtaininga to-be-used matrix mapping algorithm; and inputting the reactor core numerical calculation matrix into a to-be-used matrix mapping algorithm for automatic conversion processing to obtain a target matrix so as to realize rapid conversion of matrix data of reactor core numerical calculation in different calculation processes, reduce the programming difficulty of core calculation program codes in aserial environment or a distributed memory parallel environment, and improve the calculation efficiency. An automation function is provided for development of reactor core numerical calculation software. 本发明公开了一种堆芯数值计算矩阵的自动转换方
