MATLAB: For loop dismension mismatch

for loopMATLABmismatch

i am trying to create a variable w < 24×1 double > so I can plot it against daily hours.

idx = find(lat< 34 & lat > 33 & lon < -117 & lon > -119);
w=zeros(24,1000);
for i = 1:24
    tmp=w10(i,:,:);
    w(i,:)=tmp(idx);
end
w(w==0)=NaN;
wmean=nanmean(w,2)

but matlab gives me an error message saying dimension mismatch and I can't understand why. I also tried to create a matrix w=zeros(24,207).

my w10 is < 24x207x129 double>

I am trying to pull out wind data at specific coordination (defined by idx). Is there any other way to plot hr < 24×1 > against w < 24×1 > at the specific coordinates I gave?

Something like this, perhaps

    w=zeros(24,length(idx));
    for i = 1:24
        tmp=w10(i,:,:);
        w(i,:)=tmp(idx);
    end

MATLAB: How to modify this code to use parfor s=1:r

You could try something like this

r=20;
n=2;
m=3;
D=unidrnd(20,8,2);
upp=zeros(size(D,1),r,n);
for j=1:n
    A=unidrnd(10,m,n);
    parfor s=1:r
        B=unidrnd(10,m,n);
        C=A+B;
        % Make a temporary vector to build up in the FOR loops below
        tmp = zeros(1, size(D,1));
        for i=1:size(C,1)
            for w=1:size(D,1)
                if all(C(i,:)==D(w,:))
                    % Assign an element of 'tmp'
                    tmp(w) = 1;
                end
            end
        end
        % Assign all of 'tmp' into 'upp'.
        upp(:, s, j) = tmp;
    end
end
