for m=1:numel(myFolder)
end
for x = 1:numel(myFiles) %
for j=1:numel(myFolder)
eachFile{x}{j} = dir(myFiles{x}{j});
end
end
any idea?
This should work
for x = 1:numel(myFiles)
for y = 1:numel(myFiles{x})
eachFile{x}{j} = dir(myFiles{x}{y});
end
end

It is a number in this form a/b
Why is this happening??
Do you know how to do this in octave too?
k = (0:1000);
k_sum = sum(1./((2*k)+1).^2);
disp(k_sum)
It's interesting that you jumped straight to using syms when the basic matlab functions work perfectly well for this problem. Why is that?

I want to define a vector y=[sin(1),sin(1/2),...,sin(1/1000)].
but I don't know how to do that. I defined
for i=1:1000
y(i)=sin(1/i);
end
but this does not work.
Just define the y as the following (and initialize to get the better performance):
y = zeros(1, 1000);
for i = 1:1000
y(i) = sin(1/i);
end
Also you can do it without for:
y = sin(1./(1:1000));

I want to make a script to show me a picture like this:
https://www.dropbox.com/s/zzx2chi0jbclf66/Figura.jpg
The code is:
a = load('file.txt');
x = a(:,1);
y = a(:,4);
area(x,y)
But not like making out two colors, I think bruh command is used but not sure?

solve({4*a = 443*a1/(3.14)+a0, 7*a = 20*a1/(3.14)+a0, 105*a = 543*a1/(3.14)+a0}, {a, a1.a0});
Could someone tell me why MAPLE doens't compute this solution?
It doesn't give anything.
Thank you.
You have a typo. The second argument should be {a, a1, a0} not {a,a1.a0}
solve({4*a = 443*a1/(3.14)+a0, 7*a = 20*a1/(3.14)+a0, 105*a = 543*a1/(3.14)+a0}, {a, a1, a0});
