Dear All,

I need to rotate hyper-rectangle in 4-dimensions

but I got error Error using maketform>validate_matrix (line 317) The final column of A must consist of zeroes, except for a one in the last row. Error in maketform>affine (line 163) A = validate_matrix( A, 'affine' );

I want to transform the matrix v and their is no zeroes final column in v.

regards

maketform is complaining that the final column of trans is not [0;0;0;...;1], contrary to what the documentation demands for the case when trans is (N+1)x(N+1). You should examine the calculation of trans to see why not, and fix it.

Dear Matt,

it suppose v in my code is A and its size is 16x4 so its not square even if I add [0 0 0... 1] as last column for it.

thank you very much for pay attention and reply.

regards

That would mean that after performing the rotation, the dimension of the array has changed, which is impossible. So, you've constructed v incorrectly.
