This MATLAB function creates an arraytype identity matrix with underlying class of double, with ones on the main diagonal and zeros elsewhere.

2021-04-07 · The identity matrix is a the simplest nontrivial diagonal matrix, defined such that I(X)=X (1) for all vectors X. An identity matrix may be denoted 1, I, E (the latter being an abbreviation for the German term "Einheitsmatrix"; Courant and Hilbert 1989, p. 7), or occasionally I, with a subscript sometimes used to indicate the dimension of the matrix.

Start Hunting! 2019-10-22 2017-11-29 If n is the only input argument, then S is an n -by- n identity matrix. If n or m is 0, then S is an empty matrix. If n or m is negative, then it is treated as 0. Example: speye (4) creates a 4-by-4 identity matrix. All variables of all data types in MATLAB are multidimensional arrays. A vector is a one-dimensional array and a matrix is a two-dimensional array.

The Function Call Eye(4) Returns This Matrix: 1 0 0 0 0 1 0 0 0 0 1 If a matrix A is stored in ordinary (dense) format, then the command S = sparse(A) creates a The optional argument maxnz causes Matlab to pre-allocate storage for maxnz nonzero Perhaps the most common sparse matrix is the identity Full and Sparse Matrices. 1-47 speye.

The values in this matrix should only be equal along the diagonal elements and hence the identity is produced. As such: row = 1:n; col = row.'; row = row(ones(n,1),:); col = col(:, ones(n,1)); I = (row == col) + 0; We need to add 0 to the output matrix to convert the matrix to double precision as row == col would produce a logical matrix.
