Problem Using Interp1 Within For Loop

I have the following code:

xq = dataset(1:116,1);

Fevq = zeros(length(xq),length(Fes));

for l=1:numel(Fes);

Fevq(l)=interp1(Fo(:,l),DeltaFe56(:,l),xq);

end

Fes is a 2x1 matrix, and both Fo and DeltaFe56 are both 126x2 matrices. I would like to interpolate the values of xq onto the (Fo,DeltaFe56) curves both when l=1, and when l=2. When I try to do this, however, I get the error message, "Unable to perform assignment because the left and right sides have a different number of elements".

I would like both sides to have the size of 116x2, and I am not sure why this isn't the case. Can anybody explain why this isn't working?

Thanks,

Jonathan

Try this

xq = dataset(1:116,1);
Fevq = zeros(length(xq),length(Fes));
for l=1:numel(Fes);
    Fevq(:,l)=interp1(Fo(:,l),DeltaFe56(:,l),xq); % use Fevq(:,l) to indicate that you want to assign value to a column
end

This works perfectly, what a silly mistake on my part!
