It is important to note that the zero entries do not enter the evaluation. The operations are performed on the stored non-zero elements. This may lead to differences if compared with the same operation on a full matrix. For example, the cosine of sparse matrix is a (full) matrix with many ones.
Evaluating function resulting in NA/NaN/Inf is possible but the result cannot be used further as NA/NaN/Inf are not meaningful (yet).
All functions operate on the vector
x@entries and return the result thereof.
