Improved Algorithm for expm
The expm function now uses an improved algorithm to compute a matrix exponential.
This algorithm often requires fewer matrix multiplications.
More Efficient condest for Sparse Matrices
The condest function handles sparse matrices more efficiently when estimating a 1-norm
condition number.
accumarray Accepts Cell Vector Input
The accumarray function now accepts a cell vector as the subs input. This vector can
have one or more elements, each element a vector of positive integers. All the vectors
must have the same length. In this case, subs is treated as if the vectors formed columns
of an index matrix.
