![]() ![]() In the resultant matrix, the first 2-d matrix of matrix1 will be multiplied with the first 2-d matrix of matrix2, and in the same way, all the matrices will be multiplied.This subreddit is for discussion of mathematics. So finally, the size of the resultant matrix will be 3x5x5. The size of a two-dimensional matrix would be 5x5. Since there are three 3-d matrices, in the resultant, there also will be three 3-d matrices. Since the column number of the first 3-d matrix's 2d matrix is the same as the row number of the second 3-d matrix's 2d matrix, we can multiply the 2d matrices easily using the R-C multiplication rule.įor the matrix multiplication, we used the inbuilt matmul function of the numpy library. In the same way, we created the second matrix of size 3x2x5 of a random number which means there are three 2-d matrices of size 2 x 5 size. The size of the first matrix is 3x5x2 of a random number which means there are three 2-d matrices of the size 5x2 size. We use the random.randInt function, which will create the matrix of a given size with a value in the range we provided. We imported the humpy library in our file to use its functions. In the above program, we have two 3-d matrices, and we implemented the matrix multiplication using the numpy library. Print("matrix1:\n".format(result, result.shape)) #printing the both matrix with their sizes #creating the random three-dimensional matrix #importing the numpy library in the main file So, as we know to multiply two 2-d matrices, we follow the RXC rule in which the column number of the first matrix should be equal to the other row number of the second matrix. We can represent any three-dimensional matrix size by (i,j,k), which means there are i number of two-dimensional matrices arranged, and each two-dimensional matrix has the dimension of size jxk. Numpy is the library in a python programming language which is used for the operations of arrays. We can multiply the two three-dimensional (3-d) matrices in python using the numpy library. We cannot do the operations on the matrix of different dimensions. ![]() We can do the arithmetic operation on the matrix of the same dimension, like addition, subtraction or multiplication. In the same way, we can create the three-dimensional array by stacking the two-dimensional array or matrix in the third direction. We can create the two-dimensional matrix by arranging the many one-dimensional arrays (stack of one-dimensional arrays). One matrix can be of any dimension, such as a two-dimensional matrix, three-dimensional matrix etc. The matrix in the programming is also considered a multi-dimensional array.
