Why do I get an all-black/grayscale image when I load this PNG in MATLAB?

 There could be several reasons why you are getting an all-black/grayscale image when loading a PNG file in MATLAB. Here are some possible explanations:

  1. The image file may be corrupted or incomplete. Try opening the image in another image viewer to confirm if the issue is with the image file itself.

  2. The PNG file may have a color mode that MATLAB does not support. For example, MATLAB does not support indexed PNG images that use a color table. In this case, you may need to convert the image to a different format that is supported by MATLAB.

  3. The image file may have transparency information that is not properly handled by MATLAB. Try checking if the image has an alpha channel (transparency layer) and

Why do I get a "Too many input arguments" error when not passing any?

  I am working on some simple object-oriented code in MATLAB. I am trying to call one of my class methods with no input or output arguments in its definition. Function definition: function roll_dice Function call: obj.roll_dice; When this is executed, MATLAB says:    ??? Error using ==> roll_dice Too many input arguments. Error in ==> DiceSet>Diceset.Diceset at 11 obj.roll_dice; (etc...) Anyone have any ideas what could be causing it? Are there secret automatic arguments I'm unaware that I'm passing?   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.

Constructing piecewise symbolic function in Matlab

  I am trying to generate a piecewise symbolic function in Matlab. The reason it has to be symbolic is I want to be able to integrate/differentiate the function afterwards and/or insert actual values. I have the following function:    x^3/6 -> 0 < x <= 1 (1/6)*(-3*x^3+12*x^2-12x+4) -> 1 < x <= 2 (1/6)*(3*x^3-24*x^2+60x-44) -> 2 < x <= 3 (1/6)*(4-x)^3 -> 3 < x <= 4 0 -> otherwise I am trying to generate a piecewise symbolic function in Matlab.
