MATLAB: Error using load? File appears in workspace

load error

Hello, I'm currently trying to do a homework assignment for a MATLAB class I have. The professor gave us a matrix to perform Gaussian elimination on. I've downloaded the file, and it appears in the workspace. When I try to load the file, it gives me the error message:

Error using load Unable to read file 'y': no such file or directory.

I'm not sure where to go from here, I can't get anything else to work. Does anyone else have advice/help? I'm only a beginner, so thank you for the patience.

You don't load y. y was already in the workspace -- we can see it in the workspace panel in your screenshot! It was probably created by one of those other m-files that you had run previously. Just do "clear all" and look over your history to discover what you did to make the y spring into existence. And once it's there, it's there -- no need to try to load it or a file called y, which does not exist in your current folder as we can see from your screenshot.

MATLAB: How fill color for base load, peak load, intermediate load

Hi,

The issue is that the base value of the first area is changing when the second area is displayed when using area() function.

Try implementing the below code which involves fill() function

Hope it works!

https://www.mathworks.com/help/matlab/ref/fill.html

 f1=PSummesplit>=1e1;                              
 b1=1e1*ones(size(myDatetime(f1));
 f2=PSummesplit>=1e2;
 b2=1e2*ones(size(myDatetime(f2));
 ph=funcfill(x(f),y(f),b2,[0 0.25 0.25] ,'none');
 hold on;
 ph=funcfill(x(f2),y(f2),b3,[0 0.25 0.5],'none');
 
 
 
 function fillhandle=funcfill(xpoints,upper,lower,color,edge)    %xpoints refer xvalues, upper corresponds to upper curve values,
                                                                 % lower corresponds to lower curve values
    filled=[upper,fliplr(lower)];
    xpoints=[xpoints,fliplr(xpoints)];
    fillhandle=fill(xpoints,filled,color);
    set(fillhandle,'EdgeColor',edge,'FaceColor',color);
end
