on Grads No, but you can use NCL or R to compute EOF; and Only R or Matlab to Compute CCA ,But also you can Use NCL to compute "SVD" and after that you can compute CCA ,actually NCL have function to compute CCA ,But not efficient because its use old IBM Fortran subroutine ,so its not work fine with big array of data and may be hang in calculation ,so i prefer to use SVD function and after that you can compute CCA <br>
