I have several csv files with 64 columns and many rows. I need to extract the 1, 100,200,300 rows then reshape into 8,8 matrix and do the imaging of it. Can anyone give me some idea or guidelines to do that? Any kinds of idea will be really appreciated. For the convenience, I am attaching an example for the file.

Data = csvread(FileName);
Row = [1, 100, 200, 300];
figure;
for iRow = 1:numel(Row)
Block = reshape(Data(iRow, :), 8, 8);
AxesH = subplot(1, numel(Row), iRow);
image(AxesH, Block); % Or how do you want to display?
end
