Hi Harman,
I understand you want to know why you are getting this error. This can be overcome by changing the code in line 30 to:
lnods = fscanf(fid, '\n%d %d %d %f %f %f', [7,nelem]);
Earlier, the code did not scan through all of the values, so the next time you used the ‘fscanf’ function in line 51, no values were read.
You can learn more about the ‘fscanf’ function from the below documentation:
Hope this helps.

No, you need
lnods = fscanf(fid, '\n%d %d %d %f %d %f', [6,nelem]);
However it is better not to mix %d and %f in a single fscanf() call, as that ends up having to convert datatypes because all of the data is returned as a single vector. It would be better to use
lnods = fscanf(fid, '\n%f %f %f %f %f %f', [6,nelem]);
A %d format stops parsing at non-digits -- including stopping at decimal points or at exponential notation. The numbers %d can handle are the range -2147483648 to 2147483647 (for larger range you need %ld.) That range is easily handled by %f and %f will not stop reading if it encounters a decimal point or exponential notation.
