n= norm(X,p)returns thep-norm of matrixX, wherepis1,2, orInf: Ifp = 1, thennis themaximum absolute column sumof the matrix. Ifp = 2, thennis approximatelymax(svd(X)). This value is equivalent tonorm(X). Ifp = Inf, thennis themaximum absolute row sumof the matrix. ...
Input array, specified as a scalar, vector, matrix, or multidimensional array. Tips Ifxis a real scalar, exactly one ofisfinite(x),isinf(x), andisnan(x)returns logical1(true). For a complex scalarz,isinf(z)andisnan(z)can both return logical 1. For example,isinf(complex(Inf,NaN))an...
Create a matrix and sort its rows in ascending order based on the elements in the first column. When the first column contains repeated elements, sortrows looks to the elements in the second column to break the tie. For repeated elements in the second column, sortrows looks to the third col...

Ais singular because the rows are linearly dependent. For instance,sum(A)produces a vector of zeros. Calculate the determinant ofA. d = det(A) d = 2.6698e+10 The determinant ofAis quite large despite the fact thatAis singular. In fact, the determinant ofAshould be exactly zero! The inac...
Consider a matrix A. sort(A,1) sorts the elements in the columns of A. sort(A,2) sorts the elements in the rows of A. sort returns A if dim is greater than ndims(A). dim is not supported when A is a cell array, that is, sort only operates along the first array dimension who...

Create a matrix containing complex numbers, and sort the rows of the matrix in ascending order based on the elements in the first column. Since the magnitudes ofA(1,1)andA(3,1)are equal,sortrowscomputes their angles to break the tie. ...
