Dear all,

I found that

array1.pow(exponent)

can be done. But I need to perform the analogous operation on a vector. For example:

VectorXd a(x), b(x), c(x) ;

a = scalar * b * c.pow(0.75);

If this can also be done, could you please point that out ? Thank you.

You view any vector/matrix as an array using the .array() method, e.g.:

a = scalar * b .array() * c.array().pow(0.75);

.array() cost nothing, it only changes the semantic/API.

Thanks a lot.
