1. A data analysis method that decomposes a fundamental matrix with N rows and M columns indicating relatedness with each of first N objects and each of second M objects into three matrices, and clusters at least the first objects or the second objects, the data analysis method comprising:

  • acquiring the fundamental matrix having each element storing a value indicating the relatedness;

    setting K indicating a number of clusters of the first N objects and L indicating a number of clusters of the second M objects;

    decomposing the fundamental matrix into three matrices which are a first matrix, a second matrix, and a third matrix such that a product of the first matrix, the second matrix, and the third matrix approximates the fundamental matrix, the first matrix having N rows and K columns, the second matrix having K rows and L columns with each element at least one of a particular row and a particular column thereof storing a value falling within a predetermined range, the third matrix having L rows and M columns; and

    outputting at least one of clustering results of the first N objects and the second M objects by outputting at least one of the first matrix, the second matrix, and the third matrix.
