  • What is the geometric interpretation of the transpose?
    The determinant of a matrix tells you by what factor the (signed) volume of a parallelipiped is multipled when you apply the matrix to its edges; therefore hitting a volume in $\mathbb {R}^n$ with an orthogonal matrix either leaves the volume unchanged (so it is a rotation) or multiplies it by $-1$ (so it is a reflection)
  • PowerBI: How to transpose matrix visualization?
    I have a matrix in PowerBI that I would like to "transpose" to visualize the data differently Does anyone know how this could be done? In the pictures, the first one is my current solution and the second one is the desired layout So I would need to "turn the matrix sideways"

  • python - Transposing a 1D NumPy array - Stack Overflow
    Instead, you can transpose a "row-vector" (numpy array of shape (1, n)) into a "column-vector" (numpy array of shape (n, 1)) To achieve this you have to first convert your 1D numpy array into row-vector and then swap the shape and strides (transpose it)
  • A Cache Efficient Matrix Transpose Program? - Stack Overflow
    Steve Jessop mentioned a cache oblivious matrix transpose algorithm For the record, I want to share an possible implementation of a cache oblivious matrix transpose
  • fast bit-matrix (64x64) transpose algorithm using SIMD (ARM)
    5 I am trying to understand, if there is a fast way to do a matrix transpose (64x64 bits) using ARM SIMD instructions I tried to explore the VTRN instruction of ARM SIMD but am not sure of its effective application in this scenario The input matrix is represented as uint64 mat [64], and the output is supposed to be a bitwise transpose
  • How to transpose a 16x16 matrix using SIMD instructions?
    Now assuming there's a matrix represented by 16 SIMD registers, each holding 16 32-bit integers (corresponds to a row), how can I transpose the matrix with purely SIMD instructions? There're already solutions to transposing 4x4 or 8x8 matrices with SSE and AVX2 respectively But I couldn't figure out how to extend it to 16x16 with AVX-512 Any
