Addition of two matrices is simply performed by iterating over all of the elements and adding elements with like indices together. A c code snippet...
for (i=0; i<N; i++) for (j=0; j<M; j++) c[i][j] = a[i][j] + b[i][j];

To multiply two 3x3 matrices, you can follow these steps in your algorithm: Create a result matrix initialized to zero. Use three nested loops: the outer loop iterates over the rows of the first matrix, the middle loop iterates over the columns of the second matrix, and the innermost loop calculates the dot product by multiplying corresponding elements and summing them up. Store the computed value in the result matrix at the appropriate position. Here’s a simple Python implementation: def multiply_matrices(A, B): result = [[0 for _ in range(3)] for _ in range(3)] for i in range(3): for j in range(3): for k in range(3): result[i][j] += A[i][k] * B[k][j] return result # Example usage: A = [[1, 2, 3], [4, 5, 6], [7, 8, 9]] B = [[9, 8, 7], [6, 5, 4], [3, 2, 1]] print(multiply_matrices(A, B)) This code defines a function to multiply two 3x3 matrices and provides an example of how to use it.
For the resulting matrix, just add the corresponding elements from each of the matrices you add. Use coordinates, like "i" and "j", to loop through all the elements in the matrices. For example (for Java; code is similar in C):for (i = 0; i

Matrices can't be "computed" as such; only operations like multiplication, transpose, addition, subtraction, etc., can be done. What can be computed are determinants. If you want to write a program that does operations such as these on matrices, I suggest using a two-dimensional array to store the values in the matrices, and use for-loops to iterate through the values.
To write a program that performs arithmetic operations between two matrices using arrays, first define two 2D arrays to represent the matrices. Then, create functions for each arithmetic operation (addition, subtraction, multiplication, etc.) that iterate through the elements of the matrices, performing the operation element-wise. Ensure to handle cases where the matrices have different dimensions, as this would affect the validity of the operations. Finally, print the result matrix after each operation.

No, you cannot add a 1x3 matrix to a 3x2 matrix because the two matrices have different dimensions. For matrix addition to be valid, both matrices must have the same dimensions. In this case, a 1x3 matrix has one row and three columns, while a 3x2 matrix has three rows and two columns, making them incompatible for addition.

To combine two matrices, ensure they have compatible dimensions. If you're performing addition or subtraction, both matrices must have the same dimensions. For multiplication, the number of columns in the first matrix must equal the number of rows in the second matrix. After confirming compatibility, apply the appropriate operation element-wise for addition/subtraction, or use the matrix multiplication rules for multiplication.
Commuting in algebra is often used for matrices. Say you have two matrices, A and B. These two matrices are commutative if A * B = B * A. This rule can also be used in regular binary operations(addition and multiplication). For example, if you have an X and Y. These two numbers would be commutative if X + Y = Y + X. The case is the same for X * Y = Y * X. There are operations like subtraction and division that are not commutative. These are referred to as noncommutative operations. Hope this helps!!
