I have a wide set of splines, and at each point (x,z) of these splines is associated to a field value. I need to map all these points and relevant field values
I am trying to compute the pseudoinverse of a matrix in C code. Specifically, I am trying to compute the Moore-Penrose pseudoinverse using singular value decomp

Context: In my web app I create several groups of elements all positioned relative to each other in 3d space. All elements have transform-style: preserve-3d. A
In a matrix I would like to select a cell having a certain value (3 in the following example) and determine the number of cells having a value of 1 and 2, withi
I'm working with single-nuclei rna sequencing and I made a matrix of a subset of genes across all features that shows the counts per gene for each of them. I wa
I want to initialise two 2D matrices of size 401X401 and multiply them in a speedy way. But most probably due to stack overflow, two double 2D matrices were not
I am attempting to compute the distance matrix for an ndarray that I have converted from pandas. I tried to convert the pandas df currently in this format: move
I am trying to find the "matrix index" from values of dataframe in the Position column. The "matrix" that I would like to reference to is either a 3 x 3 or 4 x
I currently have a bool mask vector generated in Eigen. I would like to use this binary mask similar as in Python numpy, where depending on the True value, i ge
I have a list of matrix dimensions like: (1, 2), (3, 2), (2, 3), (3, 1) I want to rearrange the matrix dimensions so that all of them can be multiplied. For the
I have a simple PowerBI Matrix visualization and I need to justify columns left or right selectively. However, the Field Formatting section is not available or
Is it possible to make a delta operator like this in sympy? Im not really sure how to code it. Should be really eazy if there exists a method.
I am writing a small program of how to calculate sum of neighbours of a given position in a grid. for some reason the program does not recognize the right value
Suppose my Dataframe look like: w <- sample(-10:10, size =10) x <- sample(-10:10, size =10) y <- sample(-10:10, size =10) z <- sample(-10:10, size =
