How to do matrix multiply in MATLAB?
Matrix multiply is also known as matrix product. A single matrix is formed from this. Matrix multiplication takes about 2 seconds. There are two matrices in matrix multiply such as A and B. The product of which is matrix AB. In this math, matrix binary operation is done. To multiply two matrices in MATLAB we use * operator.
MATLAB is an high level programming language that is used by engineers and scientists to perform critical tasks. The number of rows of the first matrix row and second matrix column is the number of rows.
In this article, the steps have been given below, in which it has been explained that matrix multiply step by step process has been explained. To in depth understanding of matrix multiplication you can seek MATLAB assignment help in the UK.
Step-by-Step Process for Matrix Multiplication
Then to multiply any products, for example two products A and B, you will have to ensure that the number of column A matches the number of rows B. Thus, the product of A and B is obtained. Well, it becomes the first element of the math matrix as the first row of the first matrix is multiplied with the column of the second matrix that corresponds to its first row.
We will follow the steps given below:Step 1: In the initial stage, the first matrix must have the same number of columns as the second matrix has rows, which should be equal.
A = 1 23
4 56
7 89
Step 2: At the outset, in the second stage you will have to carry out multiplications between the components from the first row of the first matrix with components formed from the first column of the second matrix, then adding up complete multiplications. Thereupon, their uniqueness would be modified by the elements of the first row of the first matrix that have been copied with those from the second column of the second matrix, then repeat the above until we get to the locations from all the components.
1. Multiply row 1 of with column 1 of .
C[r1][c1] = (1 x 9) + (2 x 6) + (3x 3) = 9 + 12 + 9 = 30
A : Multiply row 1 of with column 2 of .
C[r1][c2] = (1 x 8) + (2 x 5) + (3 x 2) = 8 + 10 + 6 = 24
B. Multiply row 1 of with column 3 of .
C[r1][c3] = (1 x 7) + (2 x 4) + (3 x 1) = 7 + 8 + 3 = 18
2. : Multiply row 2 of with column 1 of .
C[r2][c1] = (4 x 9) + (5 x 6) + (6 x 3) = 36 + 30 + 18 = 84
a. Multiply row 2 of with column 2 of .
C[r2][c2] = (4 x 8) + (5 x 5) + (6 x 2) = 32 + 25 + 12 = 69
b. Multiply row 2 of with column 3 of .
C[r2][c3] = (4 x 7) + (5 x 4) + (6 x 1) = 28 + 20 + 6 = 54
3. Multiply row 3 of with column 1 of .
C[r3][c1] = (7 x 9) + (8 x 6) + (9 x 3) = 63 + 48 + 27 = 138
a. Multiply row 3 of with column 2 of .
C[r3][c2] = (7 x 8) + (8 x 5) + (9 x 2) = 56 + 40 + 18 = 114
b. Multiply row 3 of with column 3 of .
C[r3][c3] = (7 x 7) + (8 x 4) + (9 x 1) = 49 + 32 + 9 = 90
Step 3: To find the required product matrix in step 3, you have to replace all the elements obtained in the second step in the relevant place.
Final Resultant Matrix :
C =
3024 18
8469 54
138 114 90
Each factor can be created by multiplying corresponding rows and columns combined with the product of summation.
Which command is used to perform matrix multiplication in MATLAB?
MATLAB is a high-level programming language in which we can multiply two matrices by applying mathematical logics. Basically, we can multiply the two matrix elements by using * operators.
We can do matrix multiplication through symbol transformation. Symbol-multiplication, say taking two matrices A and B. In symbol multiplication, the variables X have to be converted into the matrix of symbol scaler S.
Conclusion
Matrix multiplication or matrix product is a very hard operation in MATLAB. Because MATLAB is a high level programming language, to understand its deep down methodology of MATLAB you can take help from programming assignment help in the UK. By following the above given steps in matrix we can easily get the output without any error. This program becomes even more perfect. In this matrix, a matrix is created by combining two pieces of information.
