Maple 2015 Error

 

 

So the above output startled me.  I have used the Maple Linear Algebra Eigenvalues, Eigenvectors commands many times with no problem.  Can any one explain to me what is going on.  The program correctly calculates the eigenvalues for the matrix which are all distinct for a real symmetric matrix, and thus should have three distinct non-zero eigenvectors, yet the eigenvectore command returns only zeros for the eigenvectors.  I calculated an eigenvector by hand corresponding to the eigenvalue of 1 and obtained (1, -sqrt(2)/sqrt(3), -1/sqrt(3).

 

So this is either a serious bug or I am going completely insane. 

HI,

 

wondered if anyone knows how to make proper use of the large operators pallete on the list of pallettes on the left. For example when using the contour integration symbol on the left how do you enter the delimiters. 

I always get the error: "Error, unable to match delimiters". The help on this is not useful for this case. 

 

Thanks. 

 

I have seen no posting on the following issue: on a high density monitor, example QHD+, where the resolution is 3200x1800, the titlebar, the palettes and the graphs are so small that they are essentially invisible. In addition, the symbols in the palettes overextend the edge of the palette. I see this with both Dell computers and Apple computers that run Maple under Windows. Is true with other computers? Is Maplesoft aware of this issue? I'm assuming it has something to do with the Java graphics library. Is there a solution?

Hello,

I am a student and using Maple to type homework assignments because of the math symbols available.  I was using Maple 17 but upgraded to 18, and its not as easy to use as 17.  For right now I am using it in text mode, because that is what I need.  But I can't figure out an easy way to do subscripts and superscripts in text mode.  Also, the "element symbol," where is it?  I feel like a lot of stuff is missing.  For instance, the arrows, the sideways triangle, lots of symbols I used before the upgrade I cant find.  Can someone help please???

Is it possible that we can add or modify new expressions in the palettes?
