acosm
matrix wise cosine inverse
Calling Sequence
t=acosm(x)
Arguments
- x
real or complex square matrix
- t
real or complex square matrix
Description
t are cosine inverse of the x
matrix. Diagonalization method is used. For nonsymmetric matrices result
may be inaccurate.One has
t=-%i*logm(x+%i*sqrtm(eye()-x*x))
Examples
A=[1,2;3,4]; cosm(acosm(A))
