چکیده
|
Here we investigate the bounds for norm of matrix functions, considering the crouzeix’s conjecture. we provide bounds for the norm of a matrix function using the numerical range and faber polynomials. in particular, we obtain bounds for norm of the sine and cosine and also the hyperbolic sine and cosine functions of matrices as exponential functions.
