Jan 20, 2019 · I get the desired output from my code (gradient descent solver function) but I am unsure of how to concatenate each set of coordinates vertically into an Nx3 matrix?

Jul 26, 2020 · The ongoing project involves creating a N X 3 matrix from a set of numbers, numbers∈[0,1,2] where each row is to be filled by a combination of these numbers, like [0,0,0], …

Jun 20, 2012 · I have a matrix that is nx3, and am trying to do the following with it: 1) For each row, sort its three entries from smallest to largest. 2) Order the rows from smallest to greatest …

Mar 24, 2018 · Suppose that A is a 3 x n matrix whose columns span R 3. Explain how to construct an n x 3 matrix D such that AD = I 3. a. For each b in R m, Ax = b has a solution. b. …

Hi all, I've got 3 matrices [nx3], made up from xyz files, and I need to combine them into: x=[a(:,1),b(:,1),c(:,1)]; y=[a(:,2),b(:,2),c(:,2)]; z=[a(:,3),b(:,3),c(:,3)]; before...

Apr 16, 2021 · I want to create an 121x3 matrix of coordinates. The X and Y coordinates go in equal steps of 800 from 0 to 8000, the Z cooridnates are always at 100. Essentially its a …

I have a matrix Nx3 (RowxCol): [[1,2,3], [4,5,6], [7,8,9]] Visually should be something like this: The idea is to get the second and third value from each row and complete the rest of spaces in the …

"how to select values of nx3 matrix where its index is equal to a value in other matrix" As far as I can tell, you can do that with basic indexing: mat = f(fnew,:)

how do I create a surface (surf) plot with a NX3 Matrix? also how do i add a colorbar to this plot? Thanks.
