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];
It works for 1 dimensional arrays of virtually any size (in this case it's 10);
#include
using std::cout;
using std::endl;
int main()
{
const int size = 5;
int arr1[size] = {1, 3, 5, 7, 9};
cout << endl << "First 1D matrix is: ";
for (int i = 0; i < size; i++)
{
cout << endl << arr1[i];
}
int arr2[size] = {2, 4, 6, 8, 10};
cout << endl << "Second 1D matrix is: ";
for (int j = 0; j < size; j++)
{
cout << endl << arr2[j];
}
int sum[size] = {0};
cout << endl << "Sum of these two matrices is a matrix with elements: "
for (int k = 0; k < size; k++)
{
sum[k] = arr1[k] + arr2[k];
cout << endl << k << " element is: " << sum[k];
}
system("PAUSE");
return 0;
}
for(i=0;i<3;i++)
{
for(j=0;j<3;j++)
{
c[i][j]= a[i][j] + b[i][j];
}
}

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

Provided both matrices are mutable, two matrices A and B can be swapped like any other two items: create temporary storage to store a copy of A, then assign B to A, and finally assign the temporary copy of the previous version of A to B. Note that in the C programming language, matrices cannot be assigned to each as such. One implementation of this algorithm might operate on the basis of references (pointers), and can thus swap two matrix references by swapping two pointers in the manner detailed above. Implementations wishing to actually transfer the data held in one matrix to another would use a library function such as memcpy() to transfer data.

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.

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!!

I assume since you're asking if 2x2 invertible matrices are a "subspace" that you are considering the set of all 2x2 matrices as a vector space (which it certainly is). In order for the set of 2x2 invertible matrices to be a subspace of the set of all 2x2 matrices, it must be closed under addition and scalar multiplication. A 2x2 matrix is invertible if and only if its determinant is nonzero. When multiplied by a scalar (let's call it c), the determinant of a 2x2 matrix will be multiplied by c^2 since the determinant is linear in each row (two rows -> two factors of c). If the determinant was nonzero to begin with c^2 times the determinant will be nonzero, so an invertible matrix multiplied by a scalar will remain invertible. Therefore the set of all 2x2 invertible matrices is closed under scalar multiplication. However, this set is not closed under addition. Consider the matrices {[1 0], [0 1]} and {[-1 0], [0 -1]}. Both are invertible (in this case, they are both their own inverses). However, their sum is {[0 0], [0 0]}, which is not invertible because its determinant is 0. In conclusion, the set of invertible 2x2 matrices is not a subspace of the set of all 2x2 matrices because it is not closed under addition.

Let me correct you: two-dimensional arrays are used in programming to represent matrices. (Matrices are objects of mathematics, arrays are objects of programming.)
