In my try.txt file, there are 9 columns with 300000 float values(300 times 1000 samples). In between every 1000 samples and in the beginning, there is some text written which I tried to skip by incrementing i appropriately. My aim is to find variance of every column with 1000 samples and repeat till the end(i.e will 300000), which will enable me to get 300 by 9 matrix.
A = dlmread(file,' ',[i 0 j 8]);
Please help me asap. I am new to matlab
