MATLAB: Does the following error come up for this short piece of code

assignment mismatchMATLAB

Hi, Whenever I try to run this code:

for i=1:3
    H=hilb(n);
    x = ones (n(i),1);
    b=H*x;
    y=mldivide(H,b);
    disp(y);
end

I get the following error: "Subscripted assignment dimension mismatch". I'm not really sure why since as far as I can see and when I set debug stops b is 5×1 and H is 5×5 on the first loop. Any help would be appreciated, Kiran

What is n? A vector? Maybe you need:

    H = hilb(n(i));

Do the sections overlap? If not, try this:

m         = zeros(1, 10);
starts    = [1 5 9];
ends      = [3 6 9];
m(starts) = 1;
m(ends)   = -1;
m         = cumsum(m);

If they sections are overlapping:

m         = zeros(1, 10);
p         = zeros(1, 10); 
starts    = [1 5 9];
ends      = [3 6 9];
m(starts) = 1;
m(ends)   = -1;
m         = cumsum(m);
p(m > 0)  = 1;

I cannot test this currently, so please keep care.

MATLAB: My if statement nestled in for loop isn’t working

I have just modified the code to get the output, and the final values for different values of M are stored in a cell.

clear all;
for M=1:3
    clear x;
    clear y;
    x(1)=0;
    y(1)=1;
    if M==1
        h=0.01;
    elseif M==2
        h=0.1;
    elseif M==3
        h=0.5;
    end
    N=1/h;
    for i=1:N
        x(i+1)=x(i)+h;
         y(i+1)=y(i)+h*(x(i)+y(i));
    end
    x1{M}=x;
    y1{M}=y;
end
