If n is the only integer input argument, then I is a square n-by-n identity matrix. If n is 0, then I is an empty matrix. If n is negative, then it is treated as 0. Identity Matrix is the matrix which is n × n square matrix where the diagonal consist of ones and the other elements are all zeros. It is also called as a Unit Matrix or Elementary matrix.

Create a 1000-by-1000 square sparse identity matrix and view the sparsity pattern. If any matrix is multiplied with the identity matrix, the result will be given matrix. The elements of the given matrix remain unchanged. In other words, if all the main diagonal of a square matrix are 1’s and rest all o’s, it is called an identity matrix.

As y contains all rows (1 to 10) you end up with same identity matrix.

74 Solvers The Identity Matrix This video introduces the identity matrix and illustrates the properties of the identity matrix. A n × n square matrix with a main diagonal of 1's and all other elements 0's is called the identity matrix I n. If A is a m × n matrix, thenI m A = A and AI n = A. Is A is a n × n square matrix, then 2020-12-04 The identity IDENTITY MATRIX matrix is a square matrix whose diagonal elements are all equal to one, with the remaining elements equal to zero. For example, the 2 x 2 identity matrix is. MATLAB has specific commands to create several special matrices. Type help specmat to see the list of special matrix commands; also check Table 2.4-4. 2011-03-09 This MATLAB function returns the block diagonal matrix created by aligning the input matrices A1,,AN along the diagonal of B.

We have already discussed vectors and matrices. In this chapter, we will discuss multidimensional arrays. However, before that, let us discuss some special types of arrays. Special Arrays in MATLAB Matrices and arrays are the fundamental representation of information and data in MATLAB ®.You can create common arrays and grids, combine existing arrays, manipulate an array's shape and content, and use indexing to access array elements. In order to create a 4 by 4 identity matrix in MATLAB, we should type this command:..
