fprintf to the command line

Hello.

having some problems getting to grips with fprintf.m.

please can you help?

If I run:

function myFunc
b=10;
for i=1:b
    fprintf('%c%c%c%c%c%c%c%c%2d of 10',8,8,8,8,8,8,8,8,i);
    pause(0.1);
end
fprintf('\n');
end

i see a nice output on the command line. great.

what I would like to produce is a progress bar. I try:

function myFunc2()
b= 10;
vec = repmat(' ', [1, b]);
vecA = ['[' vec ']'];
var = repmat('%s', [1, b+2]);
for i=1:b
    vecA(i+1) = '#';   
    fprintf(var,vecA);
    pause(0.1);
end
fprintf('\n');
end

and you see that I do not get the nice updating output on the same line, but an output which has been overwritten.

Clearly I am using fprintf wrongly. can you help? thanks

In FEX you will find Text progress bar and other text based progress bars.

that contains the fprint examples I needed. thanks
