Web2-norm of a matrix is the square root of the largest eigenvalue of ATA, which is guaranteed to be nonnegative, as can be shown using the vector 2-norm. We see that unlike the vector ‘ 2-norm, the matrix ‘ 2-norm is much more di cult to compute than the matrix ‘ 1-norm or ‘ 1-norm. The Frobenius norm: kAk F = 0 @ Xm i=1 Xn j=1 a2 ij 1 A 1=2: WebThese are different from the entrywise p-norms and the Schatten p-norms for matrices treated below, which are also usually denoted by . If m = n and one uses the same norm on the domain and the range, then the induced operator norm is a sub-multiplicative matrix norm. The operator norm corresponding to the p-norm for vectors is:
