When executing Mathematica\'s NullSpace command on a symbolic matrix, Mathematica makes some assumptions about the variables and I would like to know what they are.
I need to use a matrix class in my application for operations like Eigenvalue decomposition,LUDecomposition
I am building a 3D simulation. I am using one class to display sun, planets & moon with different size, texture, speed and orbit. Here\'s my code which does the magic job of calculating rotation
def matrixdets(a): x=(a[0][0] * a[1][1] * a[2][2]) + \\ (a[0][1] * a[1][2] * a[2][0]) + \\ (a[0][2] * a[1][0] * a[2][1])
I have a large number of entries arranged in three columns. Sample of the data 开发者_如何学Pythonis:
Given a binary matrix in which every row and col开发者_StackOverflow社区umn contains exactly only one 1, I need to rearrange the matrix columnwise so that it will become an identity matrix. For exampl
All, I\'ve got a rather frustrating problem that I think is simple, but my brain is just not working. In short, the problem is: given a sprite/image/thingy, you know that someone has rotated/translat
A couple of weeks ago I asked a question about the performance of matrix multiplication. I was told that in order to enhance the performance of my program I should use some specialised matrix classes
I\'m trying to make a 3D object do a wobble effect, very much like a boss in StarFox 64 did when it teleported (see this video at 5:17 for reference). This seems like either a skewing effect, or perha
