This is a problem when using FPRINTF to print to the screen. FPRINTF will work as expected when writing to a file.
In MATLAB 6.1 (R12.1) it is possible to get the effect you are looking for by using '\b' instead of '\r', where '\b' is the escape character for a single character backspace.
You will need to change the code a little to adjust to the '\b'. Following is an illustrative example:
ix = 1;
chars='|/-\';
fprintf(1,'%c', chars(ix)); % new line
while(1)
fprintf(1,'\b%c', chars(ix)); % modified line
ix = mod(ix,4)+1;
pause(0.05);
end
If multiple spaces need to be deleted, you may use the following code fragment:
for ix=1:numspaces
fprintf('\b')
end
