In a z matrix the column represents
WebApr 11, 2024 · Fig 1: Memory representations: row vs columnar data. Figure 1 illustrates the differences in memory representation between row-oriented and column-oriented approaches. The column-oriented approach groups data from the same column in a continuous memory area, which facilitates parallel processing (SIMD) and enhances … WebA vector could be represented by an ordered pair (x,y) but it could also be represented by a column matrix: $$\begin{bmatrix} x\\ y \end{bmatrix}$$ Polygons could also be represented in matrix form, we simply place all of the coordinates of the vertices into one matrix. This is called a vertex matrix.

WebA matrix is a rectangular arrangement of numbers into rows and columns. Each number in a matrix is referred to as a matrix element or entry . For example, matrix A A A A has 2 2 2 2 rows and 3 3 3 3 columns. WebMatrix X represents the indices of the columns needed from matrix Y. I expect to obtain a 30x128 matrix by extracting elements from matrix Y using matrix X. Is there a way to use the indices in matrix X to extract elements from matrix Y? (I tried to implement it by using torch.gather(), but the function did not give the expected results.)
