i have four arrays of different values and i have to append the arrays one after other vertically in a single array. i have tried this code
data=[i;j;blksz;avg]
but the problem i am facing is that values above 255 in array i and j are automatically normalized to 255. can anyone let me know how to fix it???

The values are being converted to the class of the first array, which appears to be uint8. How these conversions work is explained in the MATLAB documentation:

data = [double(i);double(j);double(blksz);double(avg)]
or using some suitable integer class which can contain the required values.

data = [double(i); double(j); double(blksz); double(avg)];
I suspect this could be shortened to
data = [i; j; blksz; double(avg)];
