Hi,
I am trying to insert text to the series of images being generated for each iteration in for loop. For instance, lets say for f = 1:1:200, at f = 1 ieration i need to insert text of t = 0 s likewise t = 0.0002 s, t = 0.0004 s, t = 0.0006s for f = 2, 3, 4 ans so on respectively..
Please help me with this..

Instead of recreating graphics object every iteration of your loop, it is often faster to create the object once and then update the properties:
text_handle=text(25,-35,'');
for g = 0:0.00002:0.04
text_handle.String=sprintf('t= %.5f',g);
drawnow % force graphics update
end

Ah, yes, sorry. I had at first set it print a 0 that way when initializing the object. I'll edit my answer. (you'll also have to change the FormatSpec to print the actual values, instead of telling Matlab to treat your values as integers)
