c = mpower(a,b) : computes the power of iFunc objects
@iFunc/mpower (^) function to compute the matrix-power of functions (orthogonal axes)
when one of the argument is a character string, it is used as-is in the
operator expression.
when the second argument is an integer, the initial model is extended
orthogonaly, creating a ndims(a)*b dimension model
input: a: object or array (iFunc or numeric)
b: object or array (iFunc or numeric)
output: c: object or array (iFunc)
ex: c=lorz^gauss; c=gauss^3
