What are elements of a matrix?
They are the number in the matrix.
What is a sparse matrix?
A sparse matrix is a matrix in which most of the elements are zero.
Is the scalar matrix is always a identity matrix?
No. A scalar matrix is a diagonal matrix whose main diagonal elements are the same. Only if the diagonal elements are all 1 is it an identity matrix.
How do you write a C program to find the adjoint of a matrix?
To write a C program to find the adjoint of a matrix, first, you need to create a function to calculate the cofactor of each element in the matrix. Then, construct the adjoint by transposing the cofactor matrix. The program should read the matrix size and elements from user input, compute the cofactors using nested loops, and finally display the adjoint matrix by transposing the cofactor matrix. Make sure to handle memory allocation for dynamic matrices if needed.
Define sparse matrix?
A matrix that have one or more elements with value zero.
