As I say, I do not have a saved list, but from memory:There seems to be an issue with the (generalized) eigenvalue, eigenvector routines. Try the matrix [0,1;-1,-1]. I think you will find that if the matrix is multiplied by the first returned eigenvector and the result is subtracted from the product of the first returned eigenvalue and the first eigenvector, then the result is not the zero matrix as would be expected. Similarly for the second returned eigenvalue and the second returned eigenvector. By interchanging the order of the returned eigenvalues and performing the same operation, you will get the correct result. In other words, the order of the returned eigenvalues does not match the order of the returned eigenvectors. This is not too hard to figure out for a 2x2 matrix, but I did not want to try to figure out how the order of the returned eigenvalues matches to the order of the returned eigenvectors for say an arbitrary 5x5 matrix.(reproduced)There seems to be an issue with the SVD routine. Try the matrix [1,0,0,0,2;0,0,3,0,0;0,0,0,0,0;0,4,0,0,0]. Again, I don't remember what happened the first time, but with this latest installation, I get one column of the UU matrix as "undefined".(reproduced)There seems to be an issue with the Divisors routine in number theory. With this new installation, Divisors(147) returns {1,3,7,21,49,343,147}. Note the extra element in the list. The documentation is also incorrect.(reproduced)There seems to be an issue with the Jordan canonical form routine. Try the matrix [3,-1,1;2,0,1;1,-1,2]. I do not remember what happened when I first encountered this problem, but with this latest installation, I receive an invalid list error message.(cannot reproduce, it was probably a different input)That's all I can remember for now. Maybe I can remember some others when I have a chance to think back a little.

Hmm, I never heard of that MathTools suite. Is that guy the author of it? I forgot. I don't follow math stuff for calcs very much anymore.

Google shows that there's a Bhuvanesh Bhatt on Facebook. Could someone who has a Facebook account please contact that person, in order to:* ask him whether he's the owner of http://www.ibiblio.org/technicalc/bbhatt/ and maintainer of MathTools;* if that person is the one we're looking for, point him to this topic ?Thanks in advance

permut({1,2,3}) returns [[1,2,3],[2,1,3],[3,1,2],[1,3,2],[2,3,1]] omitting the [[3,2,1]] permutation.ksubsets({1,2,3,4},2) returns [[1,2],[1,3],[1,4],[2,3],2,4]] omitting the [[3,4]] subset.
