Answer /Explanation
load hw92.dat
FID = fopen(file, 'r');
if FID == -1
fprintf('ERROR CANNOT OPEN FILE TO READ!');
else
fclose(file);
The we have:
datacell = textscan(FID, 'x%fy%f', 'CollectData', 1);
xycoords = datacell{1};
x 0 y 1
x 1.3 y 2.2
x 2.2 y 6
x 3.4 y 7.4
x 4.2 y 5.5
x 4.4 y 4.5
x 6.2 y 7.8
x 7.7 y 11.1
x 8.2 y 11.5
x 9.9 y 15.2
x 7.2 y 9.5
x 8.9 y 12.5
end
