Computer-readable recording medium storing information processing program, information processing method, and information processing apparatus

An information processing method performed by a computer, the method comprising:

• storing, in a storage, first matrix data that holds data of components of an array in a row direction;
• storing, in the storage, second matrix data that holds, in association with each piece of data in the first matrix data, a flag that indicates whether the data is in an initialized state in which data is collectively initialized in a column direction;
• storing, in the storage, third matrix data that includes an area that holds, in association with each column of the first matrix data, an initial value common to a plurality of pieces of data in the column which is regarded as an initial value of each piece of data in the column in a case where a plurality of pieces of data in the column is collectively initialized in a column direction;
• in response to reception of a first initialization request for collectively initializing a plurality of pieces of data in a first column of the first matrix data in a column direction, setting a value that indicates an initialized state to a plurality of flags of the second matrix data respectively associated with a plurality of pieces of data in the first column;
• and
• in response to reception of the first initialization request, setting a first initial value in any area of the third matrix data associated with the first column.

An information processing apparatus comprising:

• a storage, and
• a processor coupled to the memory and configured to:
• store, in the storage, first matrix data that holds data of components of an array in a row direction;
• store, in the storage, second matrix data that holds, in association with each piece of data in the first matrix data, a flag that indicates whether the data is in an initialized state in which data is collectively initialized in a column direction;
• store, in the storage, third matrix data that includes an area that holds, in association with each column of the first matrix data, an initial value common to a plurality of pieces of data in the column which is regarded as an initial value of each piece of data in the column in a case where a plurality of pieces of data in the column is collectively initialized in a column direction;
• in response to reception of a first initialization request for collectively initializing a plurality of pieces of data in a first column of the first matrix data in a column direction, set a value that indicates an initialized state to a plurality of flags of the second matrix data respectively associated with a plurality of pieces of data in the first column;
• and
• in response to reception of the first initialization request, setting a first initial value in any area of the third matrix data associated with the first column.
