A sparse matrix that is not processed is actually a special two-dimensional array in which most of the elements are 0 or other types of illegal values, with only a few non-0 elements.To implement compressed storage, you can store only non-0 elements of a sparse matrix. When you store a non-0 element in a sparse matrix, you must store the element's row and column numbers and the element values. We can encapsulate a ternary group class to store these elements.Ternary group Templatecreates a sparse

http://blog.csdn.net/yongh701/article/details/50283689In Python's numpy, the transpose of a two-dimensional array similar to array=[[1,2,3],[4,5,6],[7,8,9]], is a sentence array. T. In fact, no use of numpy, the simple use of Python, the code is not long, is also a line. Before this, however, the use of the map function and the zip (*) in Python are explained first.First, the map functionFirst, the map function in Python is very simple. Handles each i

The transpose convolution is actually equivalent to the reverse propagation of the normal convolution.
Consider an input of x=4x4, convolution kernel is w=3x3, step is stride=1,zero-padding=0
Expand the convolution kernel to a sparse matrix C:
To do convolution can be 2x2 output y,c*x=y. As shown in the following illustration:
So how do you get the transpose convolution? As we said above, the

So I figured out a way to read and display images with the OPENCV function, and the processing of the images was done by the Cuda kernel function, because the OPENCV and Cuda programming on the Windows platform was done on Visual Studio, so this method is feasible. second, the experimental process

DescriptionThe core of the fast transpose algorithm for sparse matrices is to use an array of NUM to record the number of each column in the original matrix, and use another array cpos to record the position of the first non-0 element in the new matrix for each column of the original matrix in order to achieve the purpose of fast transpose. In this way, the main hope is that after the matrix has been

Normal transformation cannot be multiplied directly by the transformation matrix. It must be multiplied by inverse transpose matrix.
Given the normal n of a vertex, and a vector u on the cut plane over the vertex, there is a transformation matrix T. U, N is the row vector, and T is the row matrix. We can see that the following conditions are met: [1]
For dx, because the row matrix is used as the transformation matrix, you can simply multiply it by
