Matrix Squared Mat Lab

For example if you want to have a matrix function identity of three columns and three rows you can write.
Matrix squared mat lab. Identity square matrix 3x3. It is denoted by the symbol. The matrix square block computes the square of an m by n input matrix u by premultiplying with the hermitian transpose. Base a is a square matrix and exponent b is a scalar.
X sqrtm a returns the principal square root of the matrix a that is x x a. If a has any eigenvalues with negative real parts then a complex result is produced. If b is a positive integer the power is computed by repeated squaring. X sqrtm a returns the principal square root of the matrix a that is x x a.
Square root of a number can be positive or negative as a square of a positive number is positive and the square of a negative number is also positive. When the input is an m by n matrix the output of the block is an n by n matrix. For other values of b the calculation involves eigenvalues and eigenvectors. Y u u equivalent matlab code the block treats length m unoriented vector inputs as an m by 1 matrix.
If a is singular then a might not have a square root. X is the unique square root for which every eigenvalue has nonnegative real part. Base a is a scalar and exponent b is a square matrix. If a is singular then a might not have a square root.
Introduction to square root in matlab square root is defined as taking the root of any square of a single element a matrix or an array.
