I have a file containing 500 by 20000 data points. I want to convert the data to images. Here is the code I used but I am getting error
s = load('Absorptiondata8.mat');
yo = s.Absorptiondata8;
columns = max(yo);
row = length(yo);
outputImage = false(row);
for k = 1 : row
outputImage(yo(k)) = true;
end
imshow(outputImage);

Ran in:
This is just a set of 6 small numbers - not a complete image where every pixel has an intensity value.
data = readmatrix('ab.txt')
data = 5×2
0.0000 0.0102 0.0000 -0.0066 0.0000 0.3177 0.0000 0.3639 0.0000 0.3138
x = data(:, 1);
y = data(:, 2);
plot(x, y, 'b.-', 'LineWidth', 2, 'MarkerSize', 40)
grid on;
Exactly how would you like to make those 6 (x,y) coordinates into an image? Would you like to use poly2mask, or perhaps exportgraphics???
