I m使用igen矩阵图书馆。
我如何能够将1* 1的矩阵转换成(float或他人)?
为此,法国
cout << ((MatrixXf(1,2) << 0, 2).finished()) * ((MatrixXf(2,1) << 0, 2).finished()) << endl;
但当我试图这样做时,我会这样做。
MatrixXf mtemp(2,1);
mtemp(0,0) = ((MatrixXf(1,2) << 0, 2).finished()) * ((MatrixXf(2,1) << 0, 2).finished());
据说不能转换Eigen:总价调换到转让中浮动。
如果mat是一个1-by-1矩阵,那么mat. Value()是其唯一一个标记条目。
因此,你可以这样做。
mtemp(0,0) = (((MatrixXf(1,2) << 0, 2).finished())
* ((MatrixXf(2,1) << 0, 2).finished())).value();
So i have a set of four points in 3D Space. P1 [0, 0, 0] P2 [128, 0, 0] P3 [0, 128, 0] P4 [128, 128, 0] Which I m then projecting orthographically to the screen effectively giving me two ...
Suppose I have an AxBxC matrix X and a BxD matrix Y. Is there a non-loop method by which I can multiply each of the C AxB matrices with Y?

Suppose we have a m by n matrix A with rank m and a set K⊆{1..n} such that the columns of A indexed by K are linearly independent. Now we want to extend K and find a set L so that k⊆L and columns ...
How do you read the following MATLAB codes? #1 K>> [p,d]=eig(A) // Not sure about the syntax. p = 0.5257 -0.8507 -0.8507 -0.5257 d = ...
I m getting a weird error when training a glmnet regression. invalid class "dgCMatrix" object: length(Dimnames[[2]]) must match Dim[2] It only happens occasionally, and perhaps only under larger ...
I need to store a 2d matrix containing zip codes and the distance in km between each one of them. My client has an application that calculates the distances which are then stored in an Excel file. ...
I am trying to create a checking program to see if the word is in a matrix horizontally or vertically. I have the code for checking the row, but would checking the column be similar to the row code? ...
