MATLAB: Read data and make (x,y) coordinates from data

datadata pointserror-checkplotsread data

There is this data file that has the format where there is a letter x, space, then the x value, letter y, space, then the y value.
x 0 y 1 
x 1.3 y 2.2 
... (continued)
how can I write a script that will makes these x and y values into points and then plot them.
finally, it should close the file and say if it was closed successfully or not.
This is what I have so far:
load hw92.dat
FID = fopen(file, 'r');
if FID == -1 
    fprintf('ERROR CANNOT OPEN FILE TO READ!'); 
else
    % I am not sure how to do make the (x,y) part
    fclose(file);
end
Not sure how to do the rest of it.

Best Answer

datacell = textscan(FID, 'x%fy%f', 'CollectData', 1);
xycoords = datacell{1};
