Functions

• coshm(A)

  matrix hyperbolic cosine.

• cosm(A)

  matrix cosine.

• expm(A, q = 7)

  Compute the matrix exponential using Pade approximation of order q.

• expm2(A)

  Compute the matrix exponential using eigenvalue decomposition.

• expm3(A, q = 20)

  Compute the matrix exponential using a Taylor series.of order q.

• funm(A, func, disp = 1)

  matrix function for arbitrary callable object func.

• logm(A, disp = 1)

  Matrix logarithm, inverse of expm.

• signm(a, disp = 1)

  matrix sign

• sinhm(A)

  matrix hyperbolic sine.

• sinm(A)

  matrix sine.

• sqrtm(A, disp = 1)

  Matrix square root

  If disp is non-zero display warning if singular matrix. If disp is zero then return residual ||A-X*X||_F / ||A||_F

  Uses algorithm by Nicholas J. Higham

• tanhm(A)

  matrix hyperbolic tangent.

• tanm(A)

  matrix tangent.

• toreal(arr, tol = None)

  Return as real array if imaginary part is small.
