2013-05-13 12:36:49 -0600 | answered a question | Problem with conjugate_transpose of a symbolic matrix Sorry, Ta was a typo and should not be there. I used dAbar = dAbar.dense_matrix() and all is good. Thanks so much tmonteil. nonlinear |

2013-05-12 15:56:25 -0600 | answered a question | Problem with conjugate_transpose of a symbolic matrix Playing around with dAbar I found that: works, but and do not work. Sorry, I didn't follow much of what link said. I do a lot of symbolic math with symbolic variables such as with t and x3 above. I know MATLAB well and Mathematica somewhat. I would prefer to support Sage. Thanks for your help. nonlinear |

2013-05-11 16:46:41 -0600 | asked a question | Problem with conjugate_transpose of a symbolic matrix I hope their is an easy answer. Thanks, nonlinear |

2013-05-06 19:18:24 -0600 | asked a question | adjoint() does not work with trig functions. adjoint() works for symbolic matrices except for those that have trig functions such as tan, sec, or tanh in their entries. Is there an easy way around this or do I need to create my own ajdoint() function? Thanks much. nonlinear |

2012-11-30 17:39:31 -0600 | commented answer | creating a matrix from blocks Thanks much, but I still get a syntax error. I have double checked the matrices A,B,C,D, and E by using print and dimensions are correct. The matrices do contain symbolic variables that have been defined using var. Any suggestions? Thanks. |

2012-11-29 12:30:58 -0600 | asked a question | creating a matrix from blocks I am new to SAGE. I need to create a matrix by using matrices of different sizes. For example: where A and B are 2x2's, C is a 2x1, D is a 1x2, and E is a 1x1. I do not need Abar to be a partitioned matrix. Thanks much. |
