matlab assignment helper

  I'm working with MATLAB GUI. When I'm trying to access the variable which was defined with the push button, it is not defined in the pop up menu. The variables; it should be set 'global', so it is defined in the whole program. And I can use it in any callback. Do you guys have any idea of how to make the variables 'global'?   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.

  What is the result of the operation A\B, where A(1, m) and B (1, m)? In the manual it is written: A\B returns a least-squares solution to the system of equations A*x= B. So it means x = inv (A'*A)*A'*B? However, the matrix A'*A is singular... Let us suppose:    A=[1 2 3] B=[6 7 6] A\B 0 0 0 0 0 0 2.0000 2.3333 2.0000 If ve use MLS: C = inv (A'*A) singular matrix C = pinv(A'*A) 0.0051 0.0102 0.0153 0.0102 0.0204 0.0306 0.0153 0.0306 0.0459 D= C*A'*B 0.4286 0.5000 0.4286 0.8571 1.0000 0.8571 1.2857 1.5000 1.2857 So results A\B and inv (A'*A)*A'*B are different...   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%...

  I have this plot  I need to make a straight  vertical  line at a point on x axis that the  user enters  and  show the coordinates of the intersection  of that vertical line with my plot. How can this be done in MATLAB? for example:  the user enters 1020 then a straight vertical line will be drawn at 1020 that meets the plot at some point and the coordinates of that point will be shown somehow.   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.

 I can convert a cell array of matrices to matrix:    >> C={[1,1]; [2,2]; [3,3]}; >> cell2mat(C) ans =      1     1      2     2      3     3 This is OK. But, I want to convert a cell array including other cell arrays to a matrix:    >> C={{1,1}; {2,2}; {3,3}};     >> cell2mat(C) Error using cell2mat (line 53) Cannot support cell arrays containing cell arrays or objects. So, desired output is:    >> mycell2mat({{1,1}; {2,2}; {3,3}}) ans =      1     1      2     2      3     3 How to do this? Edit: I want to do same thing for multidimensional ones also:    >> mycell2mat({{1,1;1,1}; {2,2;2,2}; {3,3;3,3}}) ans(:,:,1) =      1     1      1     1 ans(:,:,2) = ...

  I often need to plot 10 images together, but using this code results in small images :    img = rand(400,600); for i=1:10 subplot(2,5,i); imshow(img); title(['Image ' int2str(i)]); end As you can see, the images do not use all available space in the screen. How can I increase the size, or decrease the padding/margin between them?  Thanks for any help.   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.

There are two options: First, use the position part of the subplot:    >> subplot(2,5, i, [l, b,...

  Starting with the MATLAB char array, A:    A(1,1) = 'A' A(1,2) = 'P' A(1,3) = 'R' A(2,1) = 'M' A(2,2) = 'A' A(2,3) = 'Y' How can this be converted to a cell of strings, B, such that:    B{1} = 'APR' B{2} = 'MAY' Edit: A is a cell and using the function cellstr gives the error    Error using cellstr (line 23) S must be 2-D.

  Say if i define the following:    g = @(x) x/sqrt(x^2+1) How do i get the derivative function for g, which i can then use to evaluate at different points? I tried the symbolic math toolkit, and tried the following:    >> syms x >> f = x/sqrt(x^2+1) f = x/(x^2 + 1)^(1/2) >> diff(f) ans = 1/(x^2 + 1)^(1/2) - x^2/(x^2 + 1)^(3/2) However, i cannot figure out how to turn this into a function handle/evaluate at different points. However, i prefer doing differentiation on function_handle.
