Task 7 (20 pts.) The program task7.java given below is an incomplete program. The goal of the program is to compute the position-wise minima of two matrices (a matrix is a two-dimensional array). Complete that program, by defining a matrix min function that satisfies the following specs Function matrix mintakes two arguments, called A, B. They are both 2D arrays of double numbers If the two arrays do NOT have the same size (i.e., equal rows, and equal columns), function matrix minshould return null Otherwise, the function should return a 2D array called result, with rows and columns equal to those of A, such that the value at position (i, j) of the result is the smaller among the values at position (i,j) of A and B. IMPORTANT: You are NOT allowed to modify in any way the main function. The complete program should produce this output a: 3.2 8.0 2.1 4.9 5.3 5.7 1.1 2.2 5.5 3.3 6.6 4.4 result: 4.4 2.1 4.9 3.3 5.7
