WebOct 11, 2012 · A multidimensional array in MATLAB® is an array with more than two dimensions. In a matrix, the two dimensions are represented by rows and columns. Each element is defined by two subscripts, the row … WebDefinition : A Hilbert matrix is a square matrix with entries being the unit fraction. H i j = 1 i + j - 1. For example, the 3x3 Hilbert matrix is H = [ 1 1 2 1 3 1 2 1 3 1 4 1 3 1 4 1 5] Symbolic computations give accurate results for these ill-conditioned matrices, while purely numerical methods fail. Create a 20-by-20 numeric Hilbert matrix.
WebD = diag (v) returns a square diagonal matrix with the elements of vector v on the main diagonal. example. D = diag (v,k) places the elements of vector v on the k th diagonal. k=0 represents the main diagonal, k>0 is above … WebFeb 18, 2015 · Hi, all, Here is my problem, there is a matrix [1 2 3; 2 3 4], How to change it into the following matrix [1 2 3 0 0 0; 0 0 0 2 3 4]; Thanks a lot.
WebI = eye ('like',p) returns the scalar 1 with the same fixed-point properties and complexity (real or complex) as the prototype argument, p. The output, I, contains the same numerictype and fimath properties as p. example. I = eye (n,'like',p) returns an n -by- n identity matrix like p, with ones on the main diagonal and zeros elsewhere. example.
