i have a square matrix M of size 12x12 containing the integers from 1 to 144 rows, i want to extract the submatrix containing the coefficients m(i,j) for i + j even, can anyone help me ? 0 Comments Sign in to comment. Sign in to answer this question.Answers (2) Image Analyst ...
Iterate Through a Matrix in MATLAB Using Linear Indexing One efficient approach for iterating through matrices in MATLAB is using linear indexing. This method simplifies the iteration process, allowing you to access matrix elements using a single index. ...
How To Create A Uint8 Matrix In Matlab It should also be clear: to construct matrices you need to know the format of numbers and elements of matrices. The mathematical worksbooks go beyond that. Look at the Riemannian plane and the shape of the numbers on Wikipedia. For example, Wikipedia...
I am trying to solve the following set of matrix equations The values of r1, r2, r3 and ψare known. The values of θ and ϕ are to be found by solving this equation in matlab. i attempt to do this using the fsolve function. However, it is not able to arrive to a solution. I...
m = M_p(A==1); % extract the 3d-diagonal elements of the M_p rotation m = reshape(m,10,10); % convert single vector to matrix whose columns are the required "3d diagonal-vectors" If it is necessary that the vectors begin at 10 (i.e. i=10:-1:1 & k=10;-1:1) then use...
