MATLAB: Am I getting “Subscripted assignment dimension mismatch.”

legend

Hello,
I keep getting this error when I run the code on a certain dataset. but have used this code before without problems. For some reason it does not work past the second iteration.
for k=1:29
h(k,:) =sprintf('aircraft at %3.4f degrees latitude', parnam{1,k}.data(1,1)) ;
end

It looks like you're trying to create a 2D matrix of char(acter)s. For this to work, each char vector needs to be exactly the same length. If you are on a recent-ish version of MATLAB, a vector of string might serve you better:
h = strings(1,29);
for k=1:29
    h(k) =sprintf('aircraft at %3.4f degrees latitude', parnam{1,k}.data(1,1)) ;
end
