java - 为什么我的矩阵乘法器不起作用？

Question

public static double[][] multiplyMatrix(double[][] matrix1, double[][] matrix2) {
        // As both arrays are square and the same size, the row size represents the row size and column size for both matrices
        int dimension = matrix1.length;

        double[][] matrix3 = new double[dimension][dimension];

        for (int i = 0; i < dimension-1; i++) {
            for (int j = 0; j < dimension-1; j++) {
                for (int k = 0; k < dimension-1; j++) {
                    matrix3[i][j] += matrix1[i][k] * matrix2[k][j];
                }
            }
        }

        return matrix3;
    }

真是令人沮丧。

看起来 k 始终等于 0。您在两个循环中都递增 j。
