Hello

I have a problem implementing a mcl algorithm with Eigen SparseMatrix<float>. The documentation states that there is a cwisePow() function, but in fact there is none. I want to implement a <matlab> m2 = m .^ p; <matlab> function but got lost with power function. can someone help me pls?

Thx in advance
Peter

There is indeed no cwisePow, nor .array().pow(exponent) for sparse objects. In the meantime:

mat2 = mat.unaryExpr(Eigen::internal::scalar_pow_op<float>(p));

Thank you for the info big help.

i have a nother question there is a normalization problem, and the MatrixXf has a normalize function, but SparseMatrix has none.
dinv = diag(1./sum(m2))
m2 = m2 * dinv;
This is my matlab code. Could you help me pls?

Thx
