Matlab mldivide returns NaN when there are multiple solutions

  I have two matrices:   A = [ -1 0 0; 1 1 -1; 0 -1 1 ]; B = [-1; 0; 1]; and I want to solve the following equation: Ax=B when I use  mldivide  function I get a matrix of NaNs   X = mldivide(A,B) X = NaN NaN NaN Knowing there are multiple solutions to this problem I manually tested if one of them, namely  [1;0;1]  returns  B :   A*[1; 0; 1] and, as expected, I reassured myself that it is one of multiple solutions. So here is my question: why does  mldivide  return incorret solution?

How do I access a MATLAB UI function in another .m file?

  I am attempting to declutter my MATLAB app code by separating some of the initialization into separate .m files. For this I have set up various files for each type of component (e.g. a file for buttons, graph, etc.). I am attempting to access a function in my master initialize file from the file for buttons. My code goes as follows in the buttons .m file goes as follow:   classdef buttons < handle methods %initializes the UI function buttonCreate(app) %Create file load 1 app.fileload1 = uibutton(app.gridLayout, 'push'); app.fileload1.FontSize = 36; app.fileload1.Layout.Row = [8 9]; app.fileload1.Layout.Column = 1; app.fileload1.Text = 'Load 1'; %proceeds to create the rest of the buttons end end end Now I attempt to access the  buttonCreate()  function in my master initialize file  initialize.m :   classdef initialize < handle prop

Detect Keyboard Input Matlab

  I have a simple question, although it's harder than it seems; I couldn't find the answer on the interwebs :O I'm writing a script in Matlab. What I want to do is the following: When I press the esc key, I want a helpdialogue to pop up, so my script pauses. (So when I press esc, I want to stop the whole script to run so that the car (which im writing the script for) stops driving) How do I do this? How can I say to Matlab: When I press esc, do this... Thanks for your time guys! EDIT: It's no option to implement something which awaits the keypress. Im writing a script for a driving car. It just has to drive around basically, but when I press esc for example, it should stop driving. So the script just has to run, untill I press the esc key; then the script has to pause.

How can I make the mean of 3d matrices in a cell in Matlab?

  I have a 1x12 cell in Matlab and each element of this cell has a 3d matrix. I want to make the mean of these 3d matrices, so that I obtain a 3d matrix that has the same dimensions of each one of the 3d matrices of the cell and that is the mean of the 12 3d matrices. How can I do this operation ? I tried to extract each cell and create a 4d matrix so that I could do  mean(fourdmatrix,4)  . However, it seems not possible to create a 4d matrix. Ideed, a code like this:   cell={threedmatrixA, threedmatrixB, ...} fourdmatrix=[]; for i=1:12 fourdmatrix(i)=cell{i}; end does not work.

The input dimension of self-attention

MATLAB currently provides self-attention that can only input one sequence, but how to deal with two-dimensional images, for example, I want to input two-dimensional images composed of two sequences     NOTE:- Matlabsolutions.com  provide latest  MatLab Homework Help, MatLab Assignment Help  ,  Finance Assignment Help  for students, engineers and researchers in Multiple Branches like ECE, EEE, CSE, Mechanical, Civil with 100% output.Matlab Code for B.E, B.Tech,M.E,M.Tech, Ph.D. Scholars with 100% privacy guaranteed.

Hi, If you want to apply self-attention to two-dimensional images composed of two sequences, you can reshape the image into a single sequence and then apply the self-attention mechanism. Here's a general approach to accomplish this in MATLAB: Convert the two-dimensional images into sequences: If your two-dimensional images consist of two sequences, you can reshape each image into a single sequence.

How can I get rid of the large invisible border of my MATLAB figure without cropping it?

  Hey I have a question that would be super helpful to have an answer to. I am generating many MATLAB images. However, each image, when I copy figure to PPT, seems to have a large invisible box around it, which you can see when you click on the image. I know you can easily crop this out, but I don't want to crop many many images, and have to worry if the cropping is the same size. I want to copy these images into a Word document, and all the extra white space is not favorable. Is there a way to get that invisible box to just "hug" the image, instead of extending out several inches?     NOTE:- Matlabsolutions.com  provide latest  MatLab Homework Help, MatLab Assignment Help  ,  Finance Assignment Help  for students, engineers and researchers in Multiple Branches like ECE, EEE, CSE, Mechanical, Civil with 100% output.Matlab Code for B.E, B.Tech,M.E,M.Tech, Ph.D. Scholars with 100% privacy guaranteed.
