Web17 Sep 2024 · Definition 2.1.4: Addition of Matrices. Let A = [aij] and B = [bij] be two m × n matrices. Then A + B = C where C is the m × n matrix C = [cij] defined by cij = aij + bij. This definition tells us that when adding matrices, we simply add corresponding entries of the matrices. This is demonstrated in the next example. Web11 Mar 2024 · But in the general case, we cannot always set the sub matrices as zeros when the indice is 2. I give you an example: if we have m=5, here the indices can be [2 3] so the other sub matrices of indices (1,4) will be all zeros. Or for the same m=5 we can find indices [1 4] and here the other sub matrices of indices (2,3) will be all zeros. WebSyntax.
