WebOutput size, specified as a row vector of integers. Each element of sz indicates the size of the corresponding dimension in B.You must specify sz so that the number of elements in A and B are the same. That is, prod(sz) must be the same as numel(A). Beyond the second dimension, the output, B, does not reflect trailing dimensions with a size of 1.For example, … WebGauss-Jordan is augmented by an n x n identity matrix, which will yield the inverse of the original matrix as the original matrix is manipulated into the identity matrix. In the case that Sal is discussing above, we are augmenting with the linear "answers", and solving for the variables (in this case, x_1, x_2, x_3, x_4) when we get to row reduced echelon form (or rref).
