have large .h5 dataset that i need to read into matlab

First, I am new to matlab.

I have a large dataset that i need to read into matlab. I have already gone through all help files on read .h5 files which i don't have an issue with. however when i try to right a routine to read and then plot these files i get an error. Please see code below. The problem i have is the data files, when create, have non-sequential numbers and they change every time i run a new simulation. So i need to be able to call all the files with out knowing for certain what the numbers for each file. i thought that maybe i could use error handling to disregard the error so the program would not stop however i don't know if i could do that or if there is another way to load all the files from a folders and plot the data. the ultimate goal would be to make a movie of the data as it progresses in time, where each dataset is some time interval later in the simulation. Any help would be appreciated.

filename = 'cyc0000000.h5'; %starting filename here, check this 
nimages = 0100000;          %number of images here,  check this
[basename,remain] = strtok(filename,'0');
[start,extension] = strtok(remain,'.');
nstart=str2num(start);
for k = (nstart+1):(nstart+nimages)
    filename = strcat(basename,sprintf('%07d',k),extension);
    %
    n=hdf5read(filename, 'ne');
    plot(r,n);
end

where is r? I think that's why a error.
