acosm
matrix wise cosine inverse
Syntax
t = acosm(x)
Arguments
- x
a real or complex square matrix.
- t
a real or complex square matrix.
Description
t are cosine inverse of the x
matrix. Diagonalization method is used. For non-symmetric 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))
