![]() ![]() Sage: Bm.Inverse() # or something like thisĬonversely, with sage 8. TypeError: unable to start mathematica: End Of File (EOF). Since the GF package has a special representation for the elements of the field, we have to convert the matrix and vector entries into the special format. For me it does not work, because I do not have mathematica installed: sage: Bm = mathematica(B) If you have mathematica installed, you may use it directly from sage by doing things like below. It is customary to denote the numbers that make up the matrix, called entries, of the matrix, as the lower case version of the letter names the matrix, with two subscripts. ![]() Compute answers using Wolframs breakthrough technology & knowledgebase, relied on by millions of students & professionals. You have a bunch of those methods: sage: Natural Language Math Input Extended Keyboard Examples Upload Random. ![]() For matlab, I haven't seen _matlab_init_() method but there is a _octave_init_() method and according to Octave website " The Octave syntax is largely compatible with Matlab" : sage: A = sin(x) Mathematica Code Gaussian Elimination Download Wolfram Notebook Gaussian elimination is a method for solving matrix equations of the form (1) To perform. You want to use the method _mathematica_init_(). If your matrix A is invertible, then the sum over all of its elements is given by i, jAij 1 det (I AJ) where J are the column vectors of 2 1) Notice that the last term is the sum over all entries of the adjugate matrix of () ( j 1(B 1)) and so setting B 1 A gives the result. ![]()
