Using U,S, VT = torch.linalg.svd(M), the matrix 'M' is large, so I am getting the matrices U and VT as non orthogonal. When I compute torch.norm(torch ...

I want to initialise orthogonal weights with Keras / Tensorflow 1.14 So, I am modifying the following code (which works fine): So I am substitutin ...

I am a novice so my code will not be elegant! I'm trying to determine an optimized 'recipe' of 6 ingredients with 5 levels of use. Ingredients - (A, ...

I have a matrix A of size 50 X 6 and I have a vector x of size 50 X 1. Assume that all columns of A are orthogonal to each other. I have 2 questions: ...

I have an image which is all black and white and has a certain colored pixels over the black part, which is pink(those colored pixels are all same i.e ...

I am trying to check the orthogonality of a matrix A in c++. For that I am declaring a "MAX" value of number of rows and columns, then I am trying to ...

A board game of 8 * 8. One of the players is able to move using orthogonal movement, up to a max of 3 spaces. How do I calculate the possible steps he ...

I perform an ODR fit for given data points with x and y uncertainty with scipy.odr. For the fit result I would like to see the orthogonal distances of ...

Hi there i want to construct a sine, cosine, and sawtooth signal with a frequency of 1 Hz and a sine signal with a frequency of 2 Hz. Examine whether ...

I am currently working on a dynamic heat transfer model, using the Gekko library. The model consists of a system of partial differential equations. As ...

I need to generate a lot of random mean-invariant orthogonal matrices for my work. A mean-invariant matrix has the property A*1_n=1_n, where 1_n is a ...

I've just started a DSP course and am trying understand the big picture. As I understand it, approximating signals is needed frequently in Digital Si ...

I am working on a MATLAB task which deals with stain removal. What am I doing? I have been given a 4x4 matrix. I have then been told that it may well ...

I am trying to randomly sample 30% of a NumPy array of shape (790, 64, 64, 1). The last dimension is the channel info for the image so essentially it' ...

Say I have orthogonal vectors of dimension n. I have two questions: How to create/initialize n such orthogonal vectors in python using the existin ...

I'm working with the MEG signal and to address the problem of spatial leakage I wanted to perform orthogonalization of the time series. To have better ...

I would like some help to use R to analyze an experiment in which three groups of participants were shown two types of stimulus three times each. The ...

I need to evaluate high order (up to 4) derivatives of Chebyshev polynomials at points of the so called Chebyshev grid, x(j)=cos(πj/N), j=0,...,N An ...

Suppose there are two vector sets $A$ and $B \in \mathbb{R}^{f \times 3}$ If there is an orthogonal matrix $R \in \mathbb{R}^{3 \times 3}$ can align ...

I thought that eigenvectors had to be orthogonal to each other. The following seems to violate that. I wanted to check if I am doing something wrong. ...
